LoPy Development Board

The LoPy is the only triple bearer MicroPython enabled micro controller on the market today – perfect enterprise grade IoT platform for your connected Things. With the latest Espressif 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. It is programmable with MicroPython and the Pymakr 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.

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

PLEASE NOTE: Pycom modules are powered by the NEW and FEATURE PACKED Espressif ESP32 chip. As a result our firmware is evolving constantly as the ESP32 IDF matures. Regular firmware updates are therefore provided.
