Advanced Low-Power RF Module

The B1BMBG22Mx is an RF module utilizing the EFR32BG22C SoC series from Silicon Labs’ Gecko family. It features a 32-bit ARM Cortex-M33 processor that operates at a maximum frequency of 76.8 MHz. This module also includes a 38.4 MHz crystal oscillator, along with matching components, an antenna matching network, a low-pass filter, and a PCB antenna. It supports multiple GPIOs for LED and button peripherals. It is compatible with Bluetooth 5.2 Low Energy protocols. Additionally, it can be pre-configured with a serial interface communication protocol to facilitate easy programming.

These modules are available in two variants, differing in the number of GPIOs accessible to the user: one offers 9 GPIOs, while the other provides 13 GPIOs. All other specifications remain the same.

The B1BMBG22Mx series comprises six modules, all based on Silicon Labs' EFR32BG22C SoC family. Since the EFR32BG22C SoCs are compatible in terms of package, pins, and peripherals, these six modules are also fully pin-to-pin compatible with each other.
