BM833, BM833F, BM833E, nRF52833 Long Range Bluetooth 5.3, Thread, Zigbee Module

BM833, BM833F and BM833E are Bluetooth Low Energy, BLE 5.3 modules using Nordic nRF52833 SoC with integrated high performance PCB trace antenna.

Differences between modules:

• Size of BM833 and BM833E is 10.2x15x1.9 mm; BM833F is 10.2 (15 antenna area) x 20.6x1.9mm

• Range between two BM833s is estimated at 1400 meters at 125 Kbps; between two BM833F is estimated at 2300 meters at 125 Kbps.

BM833A and BM833AF are nRF52811 modules.

BM833 Series are footprint compatible with BM832 Series nRF52832 modules. Four main differences:

1. Supports BLE 5.1 Direction Finding.

2. Supports BLE 5 CODY PHY at 500 Kbps and 125 Kbps for longer range

3. Supports Thread and Zigbee radio protocols.

4. Operating Temperature: -40°C to +105°C

Approtect

You can lock the SWDIO port to prevent hacking for the module with a -p, for example, BM833-p. You need to use SDK 1.7.0 or newer. No product re-certification is needed. The approtect version will have a shorter lead time in the future. Order free evaluation samples.
