BM832, nRF52832 Bluetooth 5.2 Module

Full Feature BLE 5.2 module at the lowest cost

By using 2-sided PCB, BM832 has minimum BOM cost and is made in production line dedicated for Bluetooth modules with high production and quality control efficiency, the cost of using BM832 module can be lower than designing-in SoC at any quantity.

However, it is a full feature module. All 32 GPIOs of nRF52832 can be accessed. Inductors required for DCDC converted are integrated. A high performance PCB trace antenna is integrated.

BM832E is a sister module of BM832 with an u.FL connector for an external antenna.
