Bluetooth Low Energy (BLE) 5 Micro Module BC832 Ver 2.0 June 2017 BluNor BC832 is a powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) using Nordic TM nRF52832 SoC. With an ARM Cortex M4F MCU, 512KB flash, 64KB RAM, embedded 2.4GHz multi-protocol transceiver, and an integrated chip antenna. It allows faster time to market with reduced development cost. For applications needing limited number of IO pins, prototyping and production are easier using 16 castellated pins. Additional 20 LGA (Land Grid Array) pins provide access to 30 GPIOs of nRF52832 CIAA. Specications: Nordic nRF52832 with ARM Cortex M4F. 20 channel CPU independent Programmable Complete RF solution with integrated antenna Peripheral Interconnect (PPI).
