GPy

Get on with a board that gets you into the newly available LTE CAT M1 / NB1 networks. The GPy gives you full flexibility during testing, install, deployment and is delivered RCM, IC, CE and FCC certified.

With WiFi, BLE and cellular LTE CAT M1/NB1, the GPy is the latest Pycom triple-bearer MicroPython enabled micro controller on the market today the perfect enterprise grade IoT platform for your connected Things. Create and connect your things everywhere, fast.

Note: The Cellular Antenna MUST always be used with LTE CAT M1 / NB1, or it could cause serious damage to the development board.
