Fanstel BM833A Manual

BLE 5.1, 802.15.4 Modules BM833A/AF, BM833/F/E
BluNor BM833/A are powerful, highly flexible, ultra low power Bluetooth Low Energy (BLE) modules using
Nordic nRF52 SoC. With an ARM Cortex
multi-protocol transceiver, and an integrated PCB trace antenna or an u.FL for external 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 modules. The cost of using BM833A
module can be lower than designing-in SoC at any quantity. At low cost,
BM833A are full feature modules. Inductors for DCDC converter are integrated.
All 32 GPIOs are accessible.
BM833/F/E, nRF52833 modules have compatible footprint for upgrading. They
offer more GPIOs, more memories, +8 dBm TX.
"Max. TX, FCC" is the maximum TX power at antenna input measured in FCC certification testings. BM833E
max. TX power is +14 dBm with FCC certified ANT060.
