Great air quality sensor. Easy I2C interface.

For Air Quality Sensors

I interfaced the sensors on the I2C bus from an RTL8710 chip. There is an example program for the board on Github, but I used the Sparkfun BME280 and CCS811 libraries from Sparkfun. That worked fine for me as long as I used the 5A address for the CCS811 and pulled down the nWAK line for its I2C transfers. The CCS811 takes a couple of days to stabilize. Also I suspect the heater in the CCS811 is adding a couple of degrees to the temperature of the BME280 since they are in very close proximity.

But overall a nice breakout, well engineered and interesting to experiment with.

Response from Pesky Products | May 15, 2017

Thanks for the review.

Yes, the CCS811 heater will raise the board temperature a bit, especially if you run the sensor at 1 Hz. The BME280 was added to allow compensation of the CCS811 data for pressure and humidity. The latter will be slightly affected by any temperature rise due to the current usage. I measured 20 mA current (IIRC) when the heater is on, and at 0.1 Hz this shouldn't cause too much extra heating. The board design is a compromise of many factors with the goal of ease of use and small size. Other choices are possible.

Btw, does Sparkfun's program handle the humidity and pressure compensation? If not, you might be missing optimal performance from the CCS811.

THE imp003 breakout board to get!

For Electric Imp (IMP003) Development Board

Brilliant small design, using quite a few to full satisfaction for longer time now.

No downsides I can think of.....

Great Product! Have ordered multiple units.

For BQ25504 Solar Cell LiPo Charger

This is a great little unit for either plug and play solar-to-lipo charging, or as a very reasonably priced eval-style board for the BQ25504 module. Many thanks to the seller (Kris) for sharing their excellent design.

Very neat work. Super fast turn around

For ICS43432 I2S Digital Microphone

Needed these to evaluate several MEMS mics in a project I am building. The official shipping company for the components went back and forth for several weeks and then eventually came back to me saying they no longer made the breakout boards with these specific mics.

I found these, ordered them, and they were delivered and in my design before I even got an order fulfillment note from the original shipper for the other components I had ordered!

Very neat boards. Well done.

Response from Pesky Products | March 19, 2017

Thanks for the review Davyd, I am glad you like them. The newest version is the ICS43434 which offer slightly smaller size and lower power usage. When the last of the ICS43432 are gone from inventory I will make a production run of the newer version to keep these useful little mics in stock. Thanks for being a customer! Kris

MLX90621 4 x 16 IR Array

For MLX90621 4 x 16 IR Array

It is very good PCB. Especially for me who is not a professional.
Thanks to all of these people who make such projects, I can realize also my ideas and give them to my students.

François-Xavier | Feb. 19, 2017

Very good product !

For BQ25504 Solar Cell LiPo Charger

A few word to explain why this product is awesome : small, simple and efficient ! I use it to make a very small, solar powered, really very low power weather station in a remote place. Associated with a 3.6V 200mA solar cell and a big li-ion battery, it allow the weather station to work for months without sun, ans probably years if there is at least a little sun sun one day every two week !

Robert | Dec. 18, 2016

Great Service

For LSF0108 Logic Level Translator

Wiring first project now - translating 1.8v I2C and GPIO to 5v components using Intel Edison. Looking forward to this being THE SWISS ARMY KNIFE of 1.8v-5v level translators.

Francois-Xavier | Oct. 21, 2016

Very good product !

For ESP8285 Development Board

I'm very happy with this little board : small, efficient, very easy to use.
I would like to use it to make small and very low power environemental sensors, powered by small solar cells.
I have made a modified version of your script (with post to PHANT instead of a server) and have been able to have less than 8mA of current used during sleep, which is very good for my usage.
If I can ask for one improvement for the hypothetic next revision : the BME280 sensor seems to be impacted by the rest of the board (interference or just heat dissipasion of the other component, not sure yet). As you said, a small offset can be set in the code, but since the BME280 use internal temp to compensate for humidity and pression, seems that everything is a little off and it doesn't seems to be linear.
Would it be possible to add a little gab between this sensor and the others component (or a heat shield ?!) ?
I would be very happy to buy more than one of a new revision with this very little issue solved !
And, but this is for my very specific usage : a Vin pin to be able to plug my solar pannel directly on a pin, not on the USB port (maybe with a very low voltage drop diode to protect it)
Thanks a lot for this very good little board !
Francois-Xavier

Response from Pesky Products | Oct. 24, 2016

The VBAT pin on the lower left corner is a VIN pin and can accept any voltage from 3.3 to 5.5 V. If you have a LiPo battery connected to the board via the +/- port then VBAT will show the LiPo battery voltage; VBAT is connected to the + port. However, if you do not use a LiPo battery on the +/- port, then VBAT is a VIN and the board will be powered by either VIN or VUSB, whichever is the greatest voltage.

I built a flight controller with it :^)

For DC Motor Controller Board for Teensy 3.1

Usual experience with Pesky Products: in stock, quick delivery, follow his directions and you get something awesome.
Check out the flight controller I built with it (and Pesky's MPU9250 shield):

Time to order another one, for TeensyCopter Mark II !

Oleksandr | Sept. 21, 2016

Great product

For BNO-055 9-axis motion sensor with hardware fusion

The boards work perfectly.
Very pleased with communication with the Seller.
Will try the other your products as well.

Christian | Sept. 3, 2016

Beautiful board

For ESP8285 Development Board

I am impressed by how much thought went into the design of this, and I love the “appallingly small” size. I am using it with MicroPython (just playing around for now, no specific project) and everything I’ve tried works flawlessly.

I did get tracking even with the cheaper shipping option, despite the description saying otherwise, and the shipment arrived in Switzerland in 9 days.

The only thing I’m a little disappointed about is that it’s not purple anymore, I liked that color. ;)

Response from Pesky Products | Sept. 4, 2016

Thanks for the kind words!

I like purple too, but this is not an option at the fab I usually use and i got tired of assembling these myself!

Thumbs up for both electric imp and this dev board

For Electric Imp (IMP003) Development Board

I am using this product to make tools for in-house research in our R&D department.

I have been using electric imp since they introduced the first module several years back. I have found their system design to be just plain reliable and it is why I continue to use it. Most of the devices I have built are deployed remotely - actually half-way round the world and I like being able to push code to them with total confidence that it will work. My rep at the company depends on it ; )

So far as this particular dev board I used it to transition between the obsoleted imp002 and whatever comes next. I like the inclusion of the blue LED as I can use this as an error code indicator. The layout is clean and easy to work with.

: )

Matt | Aug. 11, 2016

Great little board!

For ESP8285 Development Board

Have been playing around with MicroPython and Blynk (using Arduino) on this . Great little board! I haven't figured out what I'm going to use it for long term yet, but it's great to have the very small option. Maybe for a wearable (I'm not really into that but I'm trying to encourage my 14 year old daughter to learn as much as she can about programming and microcontrollers so maybe a wearable project will induce some extra learning opportunity for her).

Response from Pesky Products | Sept. 4, 2016

I like the small aspect of this board too, and just enough GPIOs to make it interesting. I hope your daughter finds the board easy enough to use that she sticks with it, my kids seem bored with electronics:<

Dan | July 13, 2016

Fantastic product! Well made, easy to interface / program

For BNO-055 9-axis motion sensor with hardware fusion

I have been using the BNO055 for many months now, and I am extremely pleased with the product and its performance. I am using it in a custom sensor fused with GPS data to measure and track the sensor's velocity and position in inertial space. Combined with a Teensy 3.2, I can output all the data at a 50 Hz rate - fast enough to adequately sample a chaotic wind field (must have chaotic accelerations to use the accelerometer data correctly).

Adrian | July 7, 2016

High Quality

For Electric Imp (IMP003) Development Board

This board is of High Quality and well documented. I'm actually using it to develop the hardware for a startup where I work. I needed a development board for the imp003 since the imp002 was obsoleted. It has worked wonderfully. There are a few pins that are not brought out and that I use, but no complaints other than that. I have already already ordered another two boards since the first one worked flawlessly.

Response from Pesky Products | July 7, 2016

Thanks for the kind words Adrian.

I am curious which pins do you use that are not broken out on the new board design? I thought I got all of them!

Kirill | June 17, 2016

Perfect

Bought two of these for a project.
Excellent quality and customer service.
Sample code covers everything I will need to use this sensor.

Thomas | May 23, 2016

everything was great

Great product, incredible customer support

For MPU9250 Teensy 3.X add-on shields

I've ordered a few of these MPU9250 add-on shields to experiment with, my ultimate aim being to build and program my own flight controller for a micro aerial vehicle. Like many other reviewers, I've been delighted with the experience: extremely fast shipping, product works as advertised, and near-immediate response from Kris when you have a question. When I messed up my Teensy board the first time with my noobie soldering skills, he even offered to solder the headers for me! (I was more careful the second time, and am now happily using the code Kris wrote for the shield.) Thanks to makers like Kris, I've become a devoted customer of Tindie, and I look forward to buying and using more of his inventions.

Response from Pesky Products | May 25, 2016

Thanks for the kind words Simon! Customers like you keep me at it!

Ultimate Sensor fusion

For Ultimate Sensor Fusion Solution - MPU9250

If you are looking for a high quality , affordable inertial sensor, look no further. It's easy to integrate into designs thanks to very helpful examples.
Plus it's backed by excellent support. I would highly recommend it. Great product !!

Hunter | April 17, 2016

I love these

For Blackout Light

Very cool. Works exactly as described. I have a couple around my apartment as night lights. Still working after many months of use.

Michael | April 11, 2016

Awesome service!

For ICS43432 I2S Digital Microphone

Ordered Saturday, delivery on Monday via USPS. Super fast. Looking forward to hooking into a Particle Proton.

Anton | March 10, 2016

Very responsive

For Wearable BNO055 Nano Board

Shipping was fast to help us meet a deadline. It was much appreciated! The board itself is as advertised and works great.

Josh | Feb. 23, 2016

Well worth the money

For Ultimate Sensor Fusion Solution - MPU9250

This is a great board. Fast & easy & ridiculously small. Kris has proven to know the tech & is committed to continued development. Excellent communication/support. Highly recommended. Once you use a fusion board, you'll find it hard to go back to having to write code for basic orientation calculations.

Josh | Feb. 23, 2016

Good quick flash memory!

For Micron SPI Flash Memory Add-On for Teensy

Surprisingly fast flash memory on an incredibly small board. Works great on teensy (or wired to arduino).

David | Feb. 15, 2016

MPU9250 Arrived - works!

For MPU9250 Teensy 3.X add-on shields

I'm an impatient person and tend to not read directions. The MPU9250 arrived earlier today, I soldered it to the Teensy 3.2 ignoring all the I2C pin warnings listed here, made the appropriate changes to MPU9250BasicAHRC_t3.ino, and voila! It worked the first time. It is sooo tiny. Now I'm on to make it do something more interesting now that I know it is functional.

Suggestion - solder this thing to a Teensy before soldering any headers to the Teensy. I had to unsolder all the headers which is a bear with the tools I have available.

It works with Beagle Bone Black!!

For BNO-055 9-axis motion sensor with hardware fusion

Hi,

Am looking forward to getting some data off the chips. But Kris (I hope I have your name right, the owner of the Pesky Products store) helped me out answering some questions. An after a long delay on my part, I finally managed to get all the bits together, soldering, PCB board, I2C interface chip PCA 9515A. Just over the moon to see this on the screen from the I2cdetect utility on a Beagle Bone Black running Ubuntu linux. This confirms communication and the I2C address of:

BN0 055 = 0x29
BMP 280 = 0x77

Best, Mike.

ubuntu@woofietwo:~$ i2cdetect -r 1
WARNING! This program can confuse your I2C bus, cause data loss and worse!

Great "appallingly small" unit

For LiPo battery charger add-on for Teensy 3.1

I giggled at his "appallingly small" description when I first read it. And he is right, but it is exactly as described, works perfectly and I'm very happy. Bought 2 of them as soon as they came into stock again. Will be buying several more.

For documentation, the text here is more than enough. So just read it carefully. I did print the Tindie page and filed it for future reference just in case.

In my particular case, on one of my projects I needed a more robust remote mounted switch.. so just popped off the microscopic one and tacked in two leads to a larger one mounted on the case. Real easy to do, although as with working on the Teensy itself a Magnifying glass is critical. "Appallingly small" is an understatement.

Great product, thank you for making it !

Response from Pesky Products | Nov. 14, 2015

Thanks for the kind words!

If you want this or the STBC08 chargers delivered sans switch I am happy to oblige.

Charles | Oct. 26, 2015

Exellent quality, fast cheap delivery

For SPI Flash Memory Add-ons for Teensy 3.X

I can't comment on how this works yet, there are many parts to my project and it being my first it is taking me some time to code other parts before I incorporate this piece. What I can say is that it was very easy to solder even for a beginner like me. I believe a large part of this is the high quality construction. It is as the maker states "appallingly small" making it very easy to fit into the tiny space available in my project.
Delivery to the UK was very cheap and fast and I will definitely look here first if I need anything more, I will update once I have the code in place. Thank you.

Excellent sensors

For VL6180X proximity sensor

Although the sensor chip requires quite an extensive setup/configuration, once this is sorted, the performance is brilliant. Accurate and sensitive.
