What a neat little board!

For Ladybug STM32L432 Development Board

I was happy to find these. They are very compact, and with careful attention to the standby power-consumption (unlike most boards on the market) they are a great choice for battery-powered projects.

I had a small issue with component changes in the latest run, which Kris resolved quickly and fairly.

This has become my favorite board for low-powered projects.

Thanks for the kind words. This is my favorite dev board and one I use often. Just note (as you found out) the latest batch uses a 3.0 V LDO, not the 3.3 V LDO of the original.

Excellent Product, Support, and Fast Shipping!

For Firefly BLE Development Board

There is nothing better to describe other than what I wrote in the summary. Documentation is great, schematic is provided, and if you dare to challenge yourself, you can order the bare PCB from OSHPark and populate all the parts yourself that are also provided in the BOM! Thank you.

Still going strong a few years later

For Grasshopper LoRaWAN Development Board

Bought three of these a few years ago. Still going strong. Bar cutting the LED trace, everything is simple and easy.

One of the boards was in what I had mistakenly thought was a waterproof box for 18 months of wet and windy weather. I only realised the box wasn't waterproof when I took it down after a year and a half to change batteries - the board was still running perfectly though (we probably get more rain in Ireland than Kris gets in Nevada!).

Very nice board!

For Dragonfly STM32L476/96 Development Board

This is a great little ARM board. I got the STM32L496 version and have put GNAT Ada on it and have it communicating with a small Adafruit ST7789 TFT LCD.
Los of possibilities with this one!

Excellent Tracker

For Gnat LoRa+GNSS Asset Tracker

I had a question about the shipping and the seller responded very quickly. Also the item was shipped on the same day as I placed my order, I dare say within an hour. Shipping from the USA to Germany took 16 days in my case, which is less than the USPS average shipping duration to Germany of 3 weeks. And I was happily surprised that it was directly delivered to my address without paying any customs.
Last time I ordered something from the USA it was a development board for about $100 and I had to pay about 30 Euros customs, not to mention the trip to the customs office and the wait. I am glad I did not have to go through this ordeal again. I am guessing maybe because the time was shipped in a normal envelop. Very very happy.

I have ordered the Gnat to use it as a silent alarm in my bike since bike theft is very common in Germany. I received my Gnat about a week ago and although I have not yet installed it in my bike, I have been testing it indoors and playing with the code provided from Github.
I could not be happier with my device so far. At first I wasn't getting gps fix fast enough (in doors under a minute) but I was using the cheapest possible antenna. switching to a more decent gps patch antenna made a huge difference and now I get a gps fix in few seconds to a minute in doors. Motion detection is very reliable and so is communication with The Things Network over lorawan.

I have not installed it into my bike yet because I have not settled on an enclosure and battery size yet.
PS the circuit board is really really tiny. I am not familiar with the coin next to it so it was not until I received the board until i have appreciated how small is it.
from all the components that I will need to have a complete bike alarm, the battery ,battery holder, gps antenna, 868MHz antenna, box; the circuit board is the smallest.
I have a question though if anyone knows the answer to I would be very grateful: is it safe to recharge a Lithium-Ion battery using an external charger while it is connected to the Gnat ?

Thanks for the detailed review and kind words.

" is it safe to recharge a Lithium-Ion battery using an external charger while it is connected to the Gnat ? "

Depends on the type of charger but generally yes. The maximum input voltage of the Gnat is 5.5 V so as long as you don't exceed this while charging there shouldn't be a problem.

I also have a few samples of a Gnat variant that has an on-board LiPo battery charger I can make available at a discount on an "as-is" basis. If interested, e-mail me at tleracorp@gmail.com.

Awesome gadgets, awesome support

For Grasshopper LoRaWAN Development Board

Here are the instructions on how to get the boards working on your computer! (Maybe this should be a little more front and center in the docs)
https://github.com/GrumpyOldPizza/ArduinoCore-stm32l0

As others said: if your board becomes unresponsive, or the COMM port disappears from the arduino menu

1. Plug in the board to your PC. Unplug any other COMM devices that show up in the Arduino menu.
2. Hold the boot button.
3. Tap the reset button.
4. Release the boot button.
5. Go to one of the example sketches for your board and try to upload it to the board.

Your board should now reappear as a COMM device.

Great Development Board

For Grasshopper LoRaWAN Development Board

The documentation was somewhat difficult to go through, but we were able to get the functionality we needed to work. I had an issue with the module not being picked up over usb, but I got a quick response how to solve that. Just exit Arduino, plug in the kit to usb, hold the boot button, then press the reset button. Overall, the examples were great and this module was a really great way to jump right into LoRaWAN for an absolute beginner like me. The LoRaWAN_Callbacks sketch has an example a of downlink for those that may have spent a few minutes longer than they should have trying to find that example.

Glad you were able to make this work for you. Our goal is to make the Grasshopper development board easy to use but I agree we could do better on the documentation. Still, we hope programming via USB using the Arduino IDE outweighs whatever documentation deficiencies remain. The CMWX1ZZABZ-078 module is quite capable and the examples are there to help you get started. Just let us know if you have any trouble by sensing e-mail to tleracorp@gmail.com.

Excellent low power, low profile LoRA+GNSS board!

For Gnat LoRa+GNSS Asset Tracker

The quality of these boards are phenomenal. Each unit worked as advertised right out of the box and the ability to tweak settings through the arduino IDE is invaluable. It's also nice having the option for a Molex connector for further expansion.

This is the perfect little LoRA board for long deployment and low power location fixes. I don't know of any other board that offers what the Gnat does.

I would and will buy these units again.

Awesome

For Grasshopper LoRaWAN Development Board

Just received this morning, plugged, installed works like a charm without any issue.

Notice that uploading sketch to device is slow compared to Arduino Zero, but may be there is a trick.

Thanks Kriss.

Response from Tlera Corp | June 17, 2019
Thanks for the nice review. The way we organized the limited flash determines the upload rate, which is rather slow. Nothing can be done about that at the moment, no trick. I hope the functionality outweighs the inconvenience for you. Kris

The quality and design of this LoRa board is outstanding!

For Gnat LoRa+GNSS Asset Tracker

After testing many other LoRa boards and being disappointed, I found this insanely small "Gnat" board to be outstanding! The the heart of the LoRa module is a Murata design, shielded and uses an effective TCXO. When you see typical LoRa boards being advertised, they are unshielded designs which drift in frequency (not designed using a TCXO). The GNSS chip is made by u-Blox, a company I have designed-into my Telematics/IoT systems for over 8 years!

Oh, and I found the typical LoRa antennas thrown in to the board purchase to be unmatched (poor VSWR) and hence useless. The Gnat board worked so well I ordered many of the other boards from this company including the Sensor Tile, Grasshopper, and several Cricket Long boards.

All great boards which worked perfectly upon power-up!

Thanks for the kind words Joe. I am glad these devices are working so well for you!

I am working on a new design with a ZOE GNSS module and an integrated 25 mm x 25 mm passive antenna which will also use the Type AZ Murata module.

Later this year, I will introduce our first asset tracker using the STM32WB55 MCU with embedded BLE 5.0 stack along with a UBLOX GNSS engine (not sure which one yet). Lot's of exciting developments to come!

Excellent small sized and ultra-low power device

For Cricket LoRa/LoRaWAN/GNSS Asset Tracker

The Cricket is the smallest GNSS tracker I've ever seen. Kris' choice for a very compact LoRa module (Murata) combined with the performance (and size)of the u-blox CAM M8Q GNSS unit is a very smart one. Using the extensive Arduino libraries provided by his companion Thomas, it proved an rather straightforward task to built a prototype for a tracker and adapt it to the client's needs. As the design is optimized for ultra low power, we think we can meet the goal of operational lifetime of >1 year on a single battery easily. We were surprised by the performance of the u-blox GNSS unit. A location fix is quickly obtained, even indoors. Apart from the GNSS part, enough I/O capabilities are present on the device so you can use it in general IoT applications too. Highly recommended device!

Great device!

For Ladybug STM32L432 Development Board

For folks that are familiar with the Arduino family of microcontroller.
The developer personally addressed my difficulties.
I was able to get the desired -advanced- sketch for the accelerometer up and running.
(And I'm no good at C programming!)

Awesome development board/ amazing service and support!

For Dragonfly STM32L476/96 Development Board

Hi All,
This is my third board from these folks and I am super impressed!
If you do any research you will see that the STM32L496 is a a very grunty low power device...so having access to all this power thru the android IDE is really amazing.. I may still try working with it in System Workbench for STM32 (great Eclipse IDE variant) but only if I cant do what i want with arduino... I am not a sucker for punishment :-)
More than the board itself i have been very very impressed with the speed and quality of the support I have provided. I know i owe these guys some beers and perhaps some pizza ;-). Seriously I have bugged them a little more than i should but they have been awesome!
This dev board has saved me and my little company a great deal of time and hassle and I've learnt heaps (with some help as mentioned above)
So I feel this board is a super bargain so don't hestitate to buy!
Cheer,
Neal

Powerful, Well Designed, Easy to Use, Affordable

For Dragonfly STM32L476/96 Development Board

We purchased the Dragonfly STM32L496RG to prototype an STM32L496RG based embedded system. Setting up with the Arduino toolkit was quick and easy. The detailed instructions online are easy to follow and allow you to get set up and coding within 30 minutes or less. With all the source code provided, it is easy to look through the PinDescription table to understand the pin mappings and features available as well and how to access them from the Arduino environment.

Highly recommend the STM32L4 based Dragonfly boards if you need a fast and easy way to get started with the STM32L4. The processing power, light weight, and large flash memory onboard make this ideal for battery operated portable or flying electronics.

Great little board!

For Ladybug STM32L432 Development Board

It saved me a lot of time while prototyping on a host board with limited space. This low power family of MCUs is very interesting as they pack a lot of features and pretty decent amount of memory / CPU power, and I liked how Ladybug exposes all the peripheral's interfaces so it allowed me to test in a very short time that the MCU can do what was I needed it to do, and how it performs. There was no problem setting it up with GNU toolchain (to get bit better performance from it and more control than when using Arduino IDE). Great work - thank you!

Amazing new board: STM32 + Arduino right out of the box!

For Ladybug STM32L432 Development Board

As a long-time fan and successful user of the ARM Cortex M4-based Teensy board and Pesky Products shields for it, I was excited to see this new line of Arduino-compatible boards based on the hugely popular STM32 line of ARM Cortex processors (found inside nearly every flight controller on the market). Having spent several months trying (and mostly failing) to get my STM32 flight controllers working with Arduino libraries for cutting-edge sensors (like the VL53L0X ranger), I figured it was time to go back to Teensy, or wait till someone did it right, with full-on Arduino IDE and library support. Well, Tlera Corp has done it right, thanks in part to the excellent STM32L4 Arduino library from "GrumpyOldPizza" (just that name has gotta make you smile!) I followed GrumpyOldPizza's simple instructions and had my Ladybug talking to my VL53L0X, using the library from Pololu, in about 15 minutes. I still love the Teensy, but I feel like Ladybug (and Tlera's other STM32L4 based boards Dragonfly and Butterfly), with their ultra-low power consumption and floating-point capability, are going to be my default solution for new microcontroller projects from now on.

LadyBug STM32L432 Development Board

For Ladybug STM32L432 Development Board

First Look: Got a pair of these hand built (somehow) by Kris - no sign of problems - they work very well with the Arduino IDE doing what I can without soldering them so far. Impressively small and low power. Made use of the User Button easily! Reliable for uploads - and the code does what you tell it to. Now I have three add on boards to solder up for 9DOF/Mic/EEPROM. At this early stage more DOCS are on the way - but Kris is great at communication so both get 5 stars. 5 stars on the Product, and also Shipping as it was in my mailbox before I expected it to even ship.
