RF-BM-BG22A1 is a Bluetooth Low Energy 5.2 module based on EFR32BG22, one of Gecko family of SoCs from Silicon Labs, with a 32-bit ARM® Cortex®-M33 core with 38.4 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 also has a range of analog and digital interfaces such as PRS, ADC, UART, SPI, I²C, PWM, ISO 7816, IrDA, I²S, EUART and PDM. The EFR32BG22 module has the features of low power consumption, compact size, robust connection distance, and rigid reliability. 1.27-mm pitch stamp stick package for easy assembling and cost-effective PCB design. It is an ideal RF module for these low-power applications including smart plugs, building automation, security devices and systems, beacons and so on.
