Pycom LoRa module LoPy 1.0

LoPy 1.0

The LoPy is a compact triple network MicroPython enabled development board (LoRa, Wifi, Bluetooth). It’s the perfect enterprise grade IoT platform for your connected Things. With the latest Espressif ESP32 chipset the LoPy offers a perfect combination of power, friendliness and flexibility. Create and connect you things everywhere. Fast.

The LoPy can act as both a LoRa Nano Gateway and a multi-bearer (LoRa, WiFi and BLE) development platform suitable for all LoRa networks around the globe. It is programmable with MicroPython and the Pymakr plugin IDE for fast IoT application development, easy programming in-field and extra resilience with network failover. The best blend of speed to deployment and access to new LPWAN networks rolling out across Europe, USA, Africa and India. The LoPy is CE, FCC approved and is LoRaWAN certified.
