RF-BM-BG22A3 is an RF module based on EFR32BG22C224, one of Gecko family of SoCs from Silicon Labs, with a 32-bit ARM® Cortex®-M33 core with 76.8 MHz maximum operating frequency. It integrates a 38.4 MHz crystal, a matching, an antenna matching, a low-pass filter and antenna options of a meander line inverted-F PCB antenna and a half-hole interface. It supports Bluetooth 5.2 low energy, Bluetooth Mesh, Bluetooth Direction Finding AoA/AoD and proprietary and can be preprogrammed with a serial interface communication protocol for simple programming. The module also has a range of analog and digital interfaces such as PRS, ADC, UART, SPI, I²C, PWM, ISO 7816, IrDA, I²S, EUART and PDM. An integrated PA in the chip enables the module to reach up to 6 dBm TX power. It features low power consumption, compact size, robust connection distance, and rigid reliability.
