PyGo2 - Tracking and Communication Device

Meet the PyGo2 which is in essence a FiPy module on steroids! Pycom packed the FiPy in an IP6X case and gave it an OLED, a GPS, an accelerometer, some state-of-the-art antennas, and a LiPo battery. The PyGo2 features six exposed pins: 2 for power and 4 universal inputs/outputs with digital/analogue capabilities so that you can connect different types of sensors and actuators. Developers can physically connect Things and sensors to a PyGo!

Best of all, the PyGo modules are used with the Pylife Mobile App for Android and iOS and can link up with other Pycom modules. They launched the PyGo modules with the ability to mesh together at distances of up to 12 km. PyGo2 includes WiFi, Bluetooth, LoRa and dual LTE-M (embedded SIM for CAT M1 and NB-IoT from 1NCE) the PyGo2 gives access to all the world’s LPWAN networks on one tiny board.
