This board is based on our succesful Autonomo. A proven 32 bits Arduino compatible platform. It has a solar charge controller and runs on a LiPo or permanent battery.
Next we added a GPS module. We chose the Ublox Eva 7M. It’s not only very small, but with it’s assisted GPS feature it can get a fix in just seconds.
We also included a low power Accelerometer/Magnetometer chip. This means we can keep the board in sleep until it moves or has a change in magnetic field. This is crucial for developing low power devices.
Say you want to develop a bicycle tracker. You would like know the position of the bike, but only when it has moved. So keep the device in deep sleep until you detect motion. If the motion continues for a while, the bicycle may have changed position so you only then switch on the GPS to get a new reading and send this new location over the GPRS/2G network. This way you make most efficient use of you battery capacity by only using the GPS when really needed.
The Magnetometer extends the range of possibilities. You could now use the board to develop a parking sensor (fit the device in the street, if a car is parked this changes the magnetic field). Or you can mount it to a fence and use the compass direction to determine if the gate is open or not.
The board is so small (57×25 mm) you can fit it inside alsmost anything. 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.

Now that you’re using the SODAQ LoRaONE board files, you’ll be able to use our handy pin definitions. Let’s say you want to use the red LED, but you forgot that pesky pin number, you can just address the led with LED_RED inside your Arduino IDE. Our pin definitions allow you to address by name instead of pin number.
Here are all the pin definitions for the LoRaONE:
|Pin description||Pin number|
|External Switch Sense||D23|
|VCC 2G uBlox||ENABLE_2G|
