Silicon Labs EFR32BG22 Bluetooth 5.3 Low Energy Module RC224AM Compliant with AEC-Q100 automotive grade

The RC224AM is a Bluetooth 5.3 (BLE) radio frequency module designed based on Silicon Labs EFR32BG224F512IM32 SoC. The RC224AM has built-in 2.4 GHz transceiver, 38.4 MHz industrial-grade crystal oscillator and integrated high-performance serpentine antenna, which can provide a complete RF solution without additional RF design, thus shortening the product development cycle. The RC224AM fully utilizes the functions and peripheral devices of the EFR32BG22 to provide assurance and support for demanding applications, while simplifying design and reducing BOM costs.The RC224AM can be used to develop vehicle-level applications based on Bluetooth 5.3 (BLE, Bluetooth Low Energy). It can improve the reliability of operation; improve the transmission distance and anti-interference of signals; and it can also realize the problem of interoperation among different electronic products, the battery life can also be significantly extended, providing a fast BLE solution for vehicle-grade products to communicate with smart mobile devices.
