Fanstel BM833A & BM833AF Nordic nRF52811 Modules

Fanstel BM833A and BM833AF BLUETOOTH® 5.1 Thread Zigbee® Modules use the Nordic nRF52811 System-on-Chip (SoC) with an integrated high-performance PCB trace antenna. BM833A and BM833AF modules are pin-to-pin compatible with the BM832 nRF52810 modules. BM833A and BM833AF modules support BLE5.1 direction finding in addition to Thread and Zigbee radio protocols. The modules have a 97dBm sensitivity with a 1.7V to 3.6V operating voltage and a 4.6mA supply current.
