rf-star small cheap bluetooth transparent transmission module ble 4.2 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.
