EFR32BG22 0 dBm long distance Powerful AoA Beacon BLE5.2 module
RF-BM-BG22A1 is an RF module based on EFR32BG22C112F352GM32-C, 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 a meander line inverted-F PCB antenna. . Because the EFR32BG22 chips are pin-2-pin compatible in package, pins and peripherals, those three modules are pin-2-pin compatible with each other as well.
