What is it?

RSBRS02ABR(I) is a compact size, cost-effective Bluetooth low energy module based on RF-star 256 KB flash SoC RS02A1-B chip with super low power consumption, 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 (RSBRS02ABR) or an IPEX connector (RSBRS02ABRI). It supports BLE stack v5.0 and is preprogrammed with an easy-to-integrate serial interface communication protocol.
