1 Device Overview
1.1 Description
RSBRS02ABRis a compact size, cost effective single-mode Bluetooth low energy module based onRF-star256 KB
flash SoC RS02A1-B chip with super low power consumption (BLE TX: 13.0 mA @ 0 dBm, BLE RX: 12.0 mA), good
noise reduction, better sensitivity, robust transmission distance, and high reliability. The module integrates a 16 MHz
crystal, an RF matching filter, apower filter, and a meander line inverted-F PCB antenna.It supports BLE stack v5.0 and
is preprogrammed with an easy-to-integrate serial interface communication protocol.
