Pycom LoPy - LoRa+WiFi+Bluetooth MicroPython IoT Platform

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 your 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.

The board ships with or without male headers mounted as seen on the pictures.

Using the LoRa radio without the external antenna can lead to damage of the device and is therefore not recommended.

Note: Pycom modules are powered by the new and feature-packed Espressif ESP32 chip. As a result, their firmware is evolving constantly as the ESP32 IDF matures. Regular firmware updates are therefore provided.
