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. https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2025-11-03 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2025-12-03 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2025-12-20 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-01-24 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-01-26 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-02-01 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-02-06 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-02-11 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-02-20 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-03-15 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-03-22 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-03-30 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-04-01 https://elecena.pl/product/29477859/adafruit-nrf51822-bluetooth-low-energy-module 2026-04-08
