Tindie

For ATtiny3224/1614/1604 dev board Arduino compatible

I love these - I got the mega pack and there's such a great assortment of different small-sized boards. They're really great for making DIY breakouts and for projects which require a small board footprint. Definitely will be ordering more in the future.

Awesome protoboards!

It's great stuff. Just grab them, you don't know how much you need one of these little boards yet, but trust me you do.

Prompt shipping, works as described

I bought two of the no-xtal, no-regulator boards for prototyping a project. I received them within a week. They are exactly as described on the site. I found all the documentation I needed on the site (mainly the schematic) and I did not have to ask the vendor any question. I was able to load my code via the serial port using the included boot loader. I did eventually erase the boot loader because i have different requirement for my project but it did work the first time.

The most useful proto boards I've encountered

I stumbled onto these a few months ago, and as I used them for the first time recall wishing I'd found them sooner. They're quite re-workable and generally very high quality, on par with boutique electronics companies. Though these appear to be the only proto boards that are made in such supremely useful sizes and varieties. I wish Tindie had subscription orders for things like this; the thought of running out of them is mildly stressful, despite my not even knowing they existed a short time ago. Welp, Tindie requires a minimum char count for reviews, but there's no character counter on the actual review editor page, and I've forgotten what it is. I guess I could check the html source or the js console, or try submitting after each time I add a few words, at least trying to embrace brevity, but I'm highly caffeinated at the moment, so will instead continue my flowery novella, extolling the virtues of these proto boards. Oh no wait this seems to be enough characters. But yeah, thanks for this great variety and quality. Everyone should buy some of these.

Board not working

For LoRaWAN RN2483/RN2903 Breakout board (Assembled)

I think there were some QA issues with my board.... SMD components are unaligned, also ordered an 8MHz internal oscillator version, but received one with a XTAL soldered. Won't blame for the extra crystal at no cost, but makes me think seller is not checking product.

The biggest problem is board won't work at all. After shorting RST to ground, Optiboot bootloader won't come up. Tried to burn bootloader again using an USBasp, but attiny841 won't respond.

What a pity, really appreciate Spence work on github, but I'm disappointed with this board, think I wasted money.

Richard | Aug. 26, 2019

Great product let down by USPS poor export handling

Perfect product for my hardware development needs, great documentation and communication from the supplier, could not fault them in any way. It a pity USPS don't know how to handle customs procedures to the UK.

Board perfect but Software issue?

For ATtiny1634 dev. board w/Optiboot (assembled)

I have been working using your board for my projects. It really does the job. Perfect!
But I encountered an issue with your ATtinyCore. When trying to use PB3 as an IO-port it fails. I was not able to put this port into input, output or use it as an pwm. Looks like frozen. Is it restricted for internal purposes / alternate function? Can anyone help?
Regards Horst

Response from Azduino by Spence Konde | July 28, 2019

As we discussed over on github (thanks for your help investigating this), it was determined that this is a design flaw in the ATtiny1634 chip; it is listed at the very bottom of the datasheet in the errata section (what a very conspicuous location for it) - PB3 (Arduino pin 14) does not function reliably as an input when the watchdog timer is not running (for both analog and digital reads), and is internally (weakly) pulled down. A note describing this will be added to the pinout diagram on the product page and core documentation.

It works fine as an output. If the watchdog timer is enabled, it works fine for both digital and analog reads.

Just what I needed.

For LoraWAN RN2903 breakout w/PCB antenna (assembled)

I was planning to use the RN2903 with Microchip's PCB antenna for a design, but wanted to test the range performance before committing to the PCB antenna. By connecting a USB/serial converter between this board and a PC, I was able to quickly do a range test with two of these breakout boards. Make sure the USB/serial converter has a 3.3v interface, as some only have 5v signal lines.

Rebeca | Feb. 7, 2019

Great little board. Great tool.

I am using this board to help me port a project over from Attiny84 code base to the Attiny841. DrAzzy: Do you have any tips and insights on doing that ? Maybe a list of differences between the 2 processors ? anything will help. Thanks!!

Response from Azduino by Spence Konde | Feb. 7, 2019

Thanks!

That's a good suggestion - I hadn't thought of writing up a guide to migrating to ATTinyCore from other cores, and to ATTiny841 from ATTiny84.

The main differences are:
ATTiny841 has two hardware serial ports, named Serial and Serial1; they can be used like the serial ports on any other AVR through ATTinyCore. The ATTiny84 has none (though if using my core there is a builtin software serial implementation that uses the ACO vector, so it can be used without interfering with use of PCINTs for other purposes like the SoftwareSerial library would - see the ATTinyCore documentation for details - probably not relevant to you).

ATTiny841 has an additional 16-bit timer, timer2, which is identical to timer1. The PWM pin assignments are also more flexible - you can move the PWM outputs around between pins; this can allow some behavior that could never be achieved on most AVRs (unfortunately the coolest thing I did with this is covered by an NDA, so I can't go into further detail)

The ATTiny841 has a hardware SPI, and hardware I2C slave interface, while the ATTiny84 has a USI.
If using the Arduino IDE with ATTinyCore, you can use unmodified libraries designed for SPI or I2C devices, and the version of Wire and SPI libraries included with ATTinyCore for the 84 or 841 (these versions of the library automatically use the correct implementation of I2C or SPI for the hardware, and provide a compatible interface, so no changes to the library are needed). With the Arduino IDE and other cores that support the ATTiny84, you needed to use a different library for SPI/I2C that used the USI, and modify the library for the SPI or I2C device to make use of that library instead of the standard Wire or SPI library. If you are not using the Arduino IDE, you need to handle this yourself (the most notable hardship is that I2C master requires a software implementation of I2C - ATTinyCore handles this for you in Arduino-land, but if using Atmel Studio or other tools, you'd have to do this yourself)

On the ATTiny84, the internal oscillator is pretty close to 8MHz across the whole operating voltage range (ie, close enough for serial to work), but strongly temperature dependent (particularly on the low end). On the ATTiny841, the internal oscillator is very close to 8MHz across the whole temperature range below 4v, but the speed increases rapidly as voltage increases above that - such that above ~4v, it's not close enough for serial to work if you don't account for that (typically by adjusting OSCCAL). If using a crystal, which I recommend for any application where serial functionality is used (on any processor, not just this one), this is not relevant.

I've added an issue to ATTinyCore on github regarding this; you can follow this for updates on the progress towards more formal documentation. https://github.com/SpenceKonde/ATTinyCore/issues/285

Great product !

I received it after 23 days due to xxxx ( Us — Tokyo — France), nice path ;-(

So, the product is, even if in my case, I must split the PCBs, very great, the quality is there.

Great commucation ! ( due to my delivery issue)

The product is well documented, this point must be raised , thxxxx

Joshua | Nov. 16, 2018

Exactly what I was looking for!!!

For ATtiny85 Project Board

This board has all the features I needed to test out the circuit I've been working on before I order my own custom boards.. right down to the voltage regulator and mosfets.. once I had one of the boards in hand it was a joy to see everything I plan on using has a location on this board so I can fully test my circuit.
Only down side is lack of documentation (its easy enough to figure out by following the traces, but a few more labels on the board or a graphic explaining everything would save time, at least to me as I've very new to circuit design).

Steve | Oct. 25, 2018

Useful shapes for a range of projects.

For ATTiny841/84 breakout w/serial header (bare board)

Great and very useful.

I would love to see a complete range like this which all had corner mounting points......

Working great!

For 4-Channel MOSFET board with optional driver

This is the only place I was able to find these type of MOSFET's on a break out board, I'm no wiring genius, so I'm glad I did! They are working fine for me up to 50khz.

Niels | March 30, 2018

100mil grid

For 4-Channel MOSFET board with optional driver

Thanks, this board saves a lot of trouble connecting the RN2483 to my favorite controllers (pi's, samd's).
One tip though for future boards: please put all pads, and mounting holes, in a 100mil grid.
That way it's more easy to mount it on a protoboard or breadboard.
If only I could give you 4.95 stars...

Joe | Feb. 24, 2018

It's a heavy duty mosfet

I'm using these monsterfets and Arduino to control my aquarium pumps. A lot of turning on and off to try and create ocean currents and tide, with the key word being try. I was using smaller mosfets but they failed after several months. I guess I was running them too close to their rated max...These monsterfets with 2A running through them have all kinds of headroom. The temperature increase when they are running is only 2F, so I don't need heatsinks but I'm running a small load. A much better option than relays, IMO.

For ATtiny1634 dev. board w/Optiboot (assembled)

Paolo | Jan. 6, 2018

Nicely done!

TL;DR - All the love is in Azzy's ATTiny Core for the Arduino IDE. Buying his breakout boards helps to support him.

I'm incorporating a 1634 into a design I'm working on, because it has two hardware serial ports. I like to get an eval board up a running before I roll my own. Azzy's breakout board fit the bill nicely, the extra GND and VCC pins was a nice touch as I need a common ground for my motor drivers. While the project isn't open source hardware, Azzy's ATTiny Core MORE than makes up for it, and he includes the schematic.

BTW, I couldn't get Sparkfun's USBTinyISP to work and it appears I'm not alone, nor am I the type of person that will uninstall and reinstall everything just to get something to work. The AVRISP MKII works beautifully, kind of makes sense, right?

Response from Azduino by Spence Konde | Jan. 7, 2018

Thanks - glad to hear it!

The matter of ISP programmers and which ones work and don't has been a matter of some discussion. I have had similar messages from many users - people who swear that one or two programmers work great, but none of the others do. Unfortunately, there isn't much of a pattern to which the ones are reported to work, and which ones are reported not to. There is an open issue relating to problems programming with the USBTinyISP here - is this the problem you're having? https://github.com/SpenceKonde/ATTinyCore/issues/158

About all I will need to tack some SMD parts as a prototype.

For LoRaWAN RN2483/RN2903 Breakout board (Assembled)

This set covers most all of the ICs and discrete components I need to tack up into a prototype.
Documentation? Really who needs that on this kind of break out board any ways....

Michael | June 5, 2017

Great product, here's some code samples to get started.

First off, great product, super friendly customer service, although not very helpful for any kind of "getting started" advice. Maybe, they figured, if you order these things, you'd better know how to use them? Anyhow, the breakouts arrived in excellent condition, and are super easy to connect with a Raspberry Pi Zero, or other embedded-Linux (or otherwise), micro controller.

These skeleton projects on GitHub, can be used to quickly test the connectivity of your UART connection to the RN2XX3 module, on eLinux. I hope they save someone else time in working with these terrific breakouts.

If using RPi3, or RPi Zero W, please note the UART is at: /dev/ttyS0

If they save you time, and you'd like to contribute, please do.

Thank you for making these breakouts, I highly recommend them.

Good.

For 2" x 4" Prototyping/Project boards

Works fine for my purposes. Plan to buy some more.
Requirements for leaving a review are a nuisance.
Marking down communication for that reason.

Response from Azduino by Spence Konde | April 10, 2017

Thanks for your order - and looking forward to your next one! Glad to hear the boards are working out for you.

I'm sorry to hear about your experience with the product review process - unfortunately the review system is entirely managed by Tindie; as the store owner I have no control over it.

Perfect for Teensy boards

For Mint-tin size prototyping board

I agree with Michael. I needed a carrier board for a Teensy 3.5 that allowed me to break out the pins and add some connectors for my I/O. The through hole version works perfectly for that. I was able to put the Teensy straddling the center. That left room for a double row of headers on each side - one row picks up the Teensy pins and the other picks up the breadboard area. Very nice!

Michael | March 11, 2017

Azzy's Electronics prototype boards are great.

For 2" x 4" Prototyping/Project boards

I can solder through hole projects tolerably well, but I am not an expert. At the moment, I have not attempted SMD soldering.

I've been buying the various breakout boards from Azzy's Electronics for some time now. I like the fact that these boards are plated on both sides, so that you can solder components on either side of the board. The boards are better made than many of the prototype boards I've seen.

I find the boards can tolerate de-soldering and re-soldering without the pads lifting off.

The 2x4" all through-hole boards are great for large builds where I have a lot of components, or two large boards. For example, I built a Teensy 3.1 with an Adafruit Audio FX sound board and speakers on the board. I did wish the ground and power pin spacing was every 0.1" instead of every 0.2". Newer boards like the mint tin boards now have the power/ground pins every 0.1".

The mint tin boards are great for medium sized projects. The layout of the connected rows of pins allows me to stuff even more components on the board than the Adafruit mint tin board. Plus you can get a case for the board at any grocery store :-)

The 1x2" prototype board is great for adding a Teensy 3.1/3.2 with just a few connections made via wires for a small build.

The various mini-protoboards are great for breaking out small components.

The small boards are typically mailed via US post office in a normal envelop with cardboard. My last shipment of the 2x4" and mint tin boards came via US mail with a tracking number. Since I live in Massachusetts (same state as Azzy's Electronics), the boards get to me quickly.
