RF-BM-BG22A3I is an RF module based on EFR32BG22C224F512GM32-C, 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 and a low-pass filter. It supports BLE 5.2 low energy, BLE mesh, AoA / AoD and proprietary and can be preprogrammed with a serial interface communication protocol for simple programming. 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. It features low power consumption, compact size, robust connection distance, and rigid reliability. An integrated PA in the chip enables the module reach up to 6 dBm TX power. RF-BM-BG22A3I is pin-2-pin compatible with BG22A1I.


RF-BM-BG22A3I is a new product that optimized from RF-BM-BG22A3. It has IPEX antenna to achieve a longer transmission range.
