Adafruit NRF51822 Bluetooth® Low Energy Module

The custom PCB design gets a boost with an ultra-compact Bluetooth Low Energy module, featuring the Nordic nRF51822 Cortex M0 chip. Integrated with a BLE radio, supporting circuitry, and a chip antenna, it fits neatly in a tin.

Fully certified with FCC, CE, and TELEC, the module is perfect for those adept at programming with a J-Link programmer and the Nordic SDK, as it comes with a blank chip. There's no included firmware, allowing for flexible customization.

Compatible with MicroPython and offering basic Arduino support, the same chip powers the micro:bit. Ideal for embedded applications, the module requires soldering onto a PCB and code loading via an SWD programmer.
