The BLE5201 Bluetooth data transmission module uses the Bluetooth 5.2 protocol and uses the EFR32BG22C224 SOC chip from Silicon Labs. It has the characteristics of low power consumption, small size, long transmission distance and strong anti-interference ability. The BLE5201 features ultra-low transmit and receive current (3.6 mA at 0 dBm transmit; 2.6 mA receive) and a high-performance, low-power M33 core that extends coin cell battery life to ten years. Target applications include Bluetooth Mesh low energy nodes, smart door locks, personal healthcare and fitness devices. Applications such as asset tracking tags, beacons and indoor navigation will also good from the SOC’s Bluetooth Angle of Arrival (AoA) and Angle of Departure (AoD) capabilities and positioning accuracy within 1 meter. The EFR32BG22C224 SOC provides IQ sampling capability for direction finding applications and supports 125 KB and 500 KB Bluetooth Low Energy Coded PHYs, which can increase receive sensitivity to -106 dBm. Supports applications requiring direction finding capabilities or Bluetooth low energy mesh nodes. BLE5201 Bluetooth data transmission module is produced and tested strictly using lead-free process, and complies with RoHS and Reach standards.
