RF-BM-4077B2 is the first module of RF-star for automotive, it is based on Texas Instruments CC2640R2F-Q1 AEC-Q100 compliant wireless SoC supporting Bluetooth 4.2 and Bluetooth 5.0 Low Energy. The 32-bit ARM Cortex-M3 main processor at 48 MHz makes this module have high performance and lower power consumption. The module is consists of a 24 MHz crystal, a 32.768 kHz crystal, an LC balun, and an inverted-F PCB antenna. It can work under transparent transmission mode and set parameters by AT commands, which allows users to quickly build a reliable BLE connection for the applications. This module is one of the best suitable modules for the automotive industry.
