Product Description

RF-star small cheap Bluetooth transparent transmission module BLE 5.0 wireless serial module

RSBRS02ABR is a compact size, cost-effective single-mode Bluetooth low energy module based on RF-star 256 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, a power 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.

RSBRS02ABR Bluetooth module with direct-drive mode RSBRS02ABR Bluetooth module supports AT commands, romote configuration, romote reset.
