MakePython nRF52840 Dev Board

Python is one of the most widely used, simple, and easy-to-learn programming languages around. MicroPython is a lean implementation of the Python 3 programming language that has been pared down to run efficiently on microcontrollers.

MakePython nRF52840 is a powerful, generic BLE MCU module target to CircuitPython/MicroPython learners & developers. It is true “breadboard compatible”, with the very detailed pins explanation, it is easy to learn& use. The nRF52840 is ready to take advantage of the considerable performance improvements for Bluetooth Low Energy (LE) with the arrival of the Bluetooth 5 specification. Of greatest importance is the support for longer range (up to x4 compared to Bluetooth 4.x) and doubling of on-air data rate, up to 2 Mbs from 1 Mbs in Bluetooth 4.x.



This MakePython nRF52840 leads out all pins of Nordic nRF52840, programmed with CircuitPython by default, users can begin the CircuitPython developing as getting them on hand. It is also compatible with the Arduino making it easy to get started.
