This board is based on our successful Autonomo, a proven 32 bit Arduino compatible platform. It is equipped with a solar charge controller and runs on a LiPo or a permanent battery. We additionally included a GPS module: the Ublox Eva 7M to be specific. It's not only miniature but with it's assisted GPS feature it can get a fix within seconds. We've also added a low power Accelerometer/Magnetometer chip. This gives the board a nifty feature where it can stay in (deep) sleep mode until it moves or has a change in magnetic field. An essential element 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 needed, essentially increasing the battery life of your system.
Think even more out of the box with the implemented Magnetometer. Use the board to develop a parking sensor (fit the device on the street, and as soon as a car parks, it changes the magnetic field). Perhaps mount it to a fence and use the compass direction to determine whether the gate is open or not. This feature extends the range of possibilities and opens up many doors for potential projects.
The board is so small (40x25 mm) you can fit it inside almost anything (Seriously, look at the picture). To ease the development we 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.
