RF-Star Cheap CC2640R Chip Certified Bluetooth 5.0 Low Energy Modules RF-BM-4077B1L
RF-BM-4077B1L is a PCB module based on TI CC2640R2L wireless MCU supporting Bluetooth 5.1 Low Energy (BLE) stack. To minimize users’ design effort, the RF-BM-4077B1L module has integrated a 24 MHz crystal, a 32.768 kHz crystal, an LC balun, and an inverted-F PCB antenna. The CC2640 SoC contains a 32-bit ARM CortexTM-M3 main processor at 48 MHz, a rich peripheral feature set. Its 2.4GHz radio processes very low active current and outstanding RF performance.
It is pre-programmed with an application communication protocol over its serial interface and an AT command set, which allows users to quickly connect their application to build a reliable BLE connection for their products. This module fits into a wide range of BLE applications where robust connection, long battery lifetime, small form factor, and ease of use are important.
