Great unit! I wanted to use it with the low cost Dragino lg01 gateway. The lg01 is a single channel gw and hence not completely lorawan compatible. The Cricket is fully lorawan compatible, but by turning of all channels except one it works great also with a low cost gw like the dragino. The GPS and sensors works great also.

These things are a great head start to getting a custom remote sensor going. Low power, good options for onboard devices. Only comments are if running off 3xaa cells for a long term remote it will flood the supply adc input (as documented it only goes to 4.2v). Also the Accelerometer is on by default and draws around 130uA or so. It needs to be switched off in software if not being used to achieve the best results.

Overall very happy with these devices, will buy more for sure.

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!

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!)

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
