This was exactly what I was looking for. Using it to monitor moisture levels for some young citrus trees (in conjunction with some DF Robot moisture sensors and Adafruit feathers). Using 6v 136x110mm solar panels and a variety of lipos. Been working long well for several weeks now. Was looking for something small and with a battery monitor built in which is surprisingly difficult to find. Will buy again if they reappear!

Thank you so much, I am happy that you liked it and it solved you purpose :-)

great board for TTN V.3

For LoRaWAN-megaBrick

Thanks for fast shipping (received within 3 day). my solder iron will warm up soon
I think this board is a great value for migrating to TTN V.3 with the new and huge MCCI library (probably you update the documentation?)
on the schematic there is missing JL, and RST on the board is marked as JP1. that's what I've seen so far

Just what I needed a Atmel328 + Lora module

For LoRaWAN-miniBrick

And it is in a small package. I would like a few more ground and 3.3 volt pin. They are always handy when hooking up external sensors.

Too good to disappear

For LoRaWAN-megaBrick

I'm very pleased LPD/LPS are back again with this LoRaWAN development board. I was sad when the LoRaWAN Mini disappeared. I wanted to buy more but when it disappeared from Tindie I thought I would have to make my own... until I saw this updated version with more flash memory - great! To be honest the LoRaWAN Mini didn't have enough memory for both a LoRaWAN stack and an Adafruit soil sensor.

This megaBrick is professionally assembled to high quality with lead free solder (I don't like lead free for hobby use but lead free is the professional choice when you sell products). I would like to upload a photo but Tindie doesn't let me. It doesn't waste power on inefficient regulators or LEDs (unless you solder a link) so it can run for over a month on a 400mAh battery (with the 'LowPower' library), probably a lot longer with reduced transmissions (my tests sent a transmission every 10 minutes).

I wish LPS every success with this megaBrick and I hope it remains available for a long time. However in case it disappears soon, I recommend any purchaser to save/download the product page and schematic asap. Also a recommendation for LPS; the Tindie product page is good but doesn't print cleanly (Tindie website problem) so it would be helpful to have a downloadable PDF with the product specs, usage information and schematic.

Message to LPS: if you improve the technical documentation by making it downloadable (printing the Tindie page doesn't work) I will increase my documentation review from 4 to 5 stars.

Thanks

Thank you so much for the great review, I appreciate :-). As per your feedback I have added the printable version (PDF) of the documentation which also includes schematic, please check product page.
Regarding your low power application. I am working on a base board for megaBrick which will include, apart from other useful things, an RTC that can be used as an external wake-up source. Using this, will allow going into deep sleep with RTC as a wake-up source.
