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 5.3 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 EFR32BG22 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. The low power consumption, compact size, robust connection distance, and rigid reliability make it be sought after by asset tags and beacons, consumer electronics, building automation, Bluetooth Mesh low power nodes and portable medical devices.
