RF-BM-S02I Bluetooth 4.2 LE module is based on Texas Instruments CC2540 SoC with a low-power 8051 core. The module consists of a 32 MHz crystal, a 32.768 kHz crystal, an LC balun, and an IPEX connector for RF signal output. This module with up to 4 dBm TX power and the IPEX connector makes it have more possibilities in a long range application. It can be pre-programmed with the BLE master or slave protocol, which enables you to have a quick start of the product design. And this module is pin-2-pin compatible with a wide range of RF-star BLE modules from BLE4.2 to BLE5.2.
