This is the third generation of the successful SODAQ ONE board with US 915MHz LoRa radio.

SKU: SODAQ-ONE-US-RN2903-V3 Categories: , ,


This is the US version (915MHz)


This is the third generation of the successful SODAQ ONE board. It is equipped with a solar charge controller and runs on a LiPo or a permanent battery. It has the Ublox Eva 8M GPS module which is not only miniature but with it’s assisted GPS feature it can get a fix within seconds. They’ve now added an extremely low power Accelerometer/Magnetometer. This gives the board a nifty feature where it can stay in (deep) sleep mode until it moves. An essential feature for developing low power devices.Let’s imagine you want to develop a bicycle tracker using the SODAQ ONE. You would like to track the position of the bike, but only when it has moved. This is possible if you keep the device in deep sleep until it detects motion. If the motion continues for a while, the bicycle may have changed position so only then the GPS will switch on to get a new reading and send this location over the LoRa network. Efficient right? This system will allow you make most efficient use of your battery capacity by only using the GPS when really needed, essentially increasing the battery life of your system.

The board is so small (45×25 mm) you can fit it inside almost anything (Seriously, look at the picture). To ease the development they have fitted two rows of headers so you can use it on a breadboard. Why? Well, it has 14 free I/O lines that you can use for your own purpose. Whether you want to build a weather station, control street lights or get a signal when you have received (snail) mail. It’s all possible with the SODAQ ONE.

New in this version is that they have added JST headers (receptacles) so you can now directly plug in a LiPo battery and Solar Panel if you like.

Intended use
The SODAQ ONE is a development/evaluation tool intended for the evaluation of Microchip wireless modules in a Research and Development laboratory environment. It is not a Finished Appliance. Manufacturers who integrate SODAQ ONE in a Finished Appliance must take responsibility to follow regulatory guidelines, for example for CE marking and and EC compliance .
