BLE5.1Module BM833A/AF Data SheetsVer 0.90 July 2019

BluNor BM833A/AF are powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) modules using

Nordic nRF52811 SoC. With an ARMCortex

M4(F) MCU, 192KB flash, 24KB RAM, embedded 2.4GHz multi-

protocol transceiver, and an integrated PCB trace antenna. It allows faster time to market with reduced

development cost.

BM833A/AF are designed to minimize PCB cost and to maximize efficiency in production line

dedicated for Bluetooth module. The cost of using BM833A/AF modules can be lower than

designing-in SoC at any quantity. At low cost, BM833A/AF offer full features. Inductors for DCDC

converter are integrated. All 32 GPIOs are accessible.

Bluetooth ranges are estimated in environments with Low Multiple Path Interference. Bluetooth

range is much shorter in environments with radio frequency interference and severe multiple path interference.

Array antenna required for Angle of Arrival (AoA) and Angle of Departure (AoD) direction finding is supported in

BT Series modules.

BLE5.1Module BM833A/AF Data SheetsVer 0.90 July 2019 Suggestion for Battery Power Application Standby current consumption is important for battery-powered product. We suggest adding a 32.768 kHz crystal and 2 capacitors as shown in the upper left corner of the evaluation board schematics. The 32MHz main clock won’t be active at idle state to save power. Two inductors required for DCDC converter are inside BM833A module. You can enable DCDC to lower power consumption.
