TI CC2640R2F RF-BM-4077B1 long distance small size BLE5.0 Bluetooth module
RF-BM-4077B1 is a PCB module based on TI CC2640 wireless MCU supporting Bluetooth Low Energy (BLE) stack v4.2 or BT5.0. To minimize users’ design effort, RF-BM-4077B1 module has integrated a 24 MHz crystal, a 32.768 kHz crystal, an LC balun, and an inverted-F PCB antenna. The CC2640 device contains a 32-bit ARM CortexTM-M3 main processor at 48 MHz, a rich peripheral feature set including a unique ultra-low power sensor controller. 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.
