BLE DEV.N R3 (nRF51822 powered board for Bluetooth Low Energy Fun)

We just released the 3th revision of the BLE DEV.N board. It has a nice battery holder and reset button (bottom side), so much for a such small size. You can check the BLE.DEV.N R3 UM v1.0 document for detailed description. It will allow you easy to develop your next project but this time also to power it with a CR1216 battery, in order to become real “wireless” product.

  • 32 bit, ARM Cortextâ„¢ M0
  • Access to all pins
  • Easy tracing via printf redirecting to serial communication port
  • 4 LEDs (1 Green, 1 Red, 1 Yellow, 1 Blue), 2 user buttons
  • Hardware improvements over R1
  • Upload custom code using on board USB-Serial connection, removing the need of external/additional programmer BLE DEV.N DFU v1.0 (BLE DEV.N Device Firmware Updates)
  • BLE.DEV.N R3 UM v1.0 BLE.DEV.N User Manual R3 v1.0
  • Board can be programmed with J-Trace for Cortex-M, ST-LINK/V2, ST-LINK/V2 from STM32F3DISCOVERY and of course over the Air and USB via pre-programmed bootloader
  • RESET button, added in R3
