In addition to the Expansion Board, two additional sensor boards for the Pycom modules are available, which are ideal for quickly building a fully functioning IoT solution. These little boards fit all Pycom modules and each contain a number of sensors.
Pytrack is intended for use in GPS applications such as asset tracking or monitoring. Pytrack has a super accurate GNSS + Glonass GPS and a 3 axis 12-bit accelerometer. This board has also USB port with serial access, LiPo battery charger and MicroSD card compatibility.
To simplify usability, APIs for the libraries of the sensors have been created.
