BM833F
Overview
The BM833F is a high-performance Bluetooth 5.1 and 802.15.4 wireless module based on the Nordic nRF52833 SoC. It features an integrated ARM Cortex-M4F processor, 512kB Flash, and 128kB RAM, making it capable of handling complex application code alongside the wireless stack. The module includes a built-in PCB trace antenna and is designed for easy surface-mount integration into space-constrained IoT designs.
Why Choose This Part
The module offers a significant link budget with +8dBm TX power and -104dBm sensitivity (in Long Range mode), ensuring reliable connections. It simplifies power management with an integrated DC-DC converter and embedded inductors, while supporting a wide supply voltage range from 1.7V to 5.5V. The inclusion of NFC-A and 42 GPIO pins provides extensive flexibility for peripheral interfacing and secure out-of-band pairing.
