Texas Instruments TI CC2640 BLE 5.3 module RC2640A with PCB Antenna

The RC2640A module is designed based on CC2640R2FRSM Bluetooth Smart BT 5.0 System-on-Chip, fully supports the single-mode Bluetooth Low Energy operation. The module contains a 32-bit ARM Cortex^TM-M3 processor, with the working frequency at 48.0 MHz which is the same as the main processor. The module has rich peripherals function libraries, and a unique ultra-low-power sensor controller, which is fit for connecting the external sensors in the sleep mode and/or acquiring analog and digital data independently. It supports BLE stack v5.0 and is preprogrammed with an easy-to-integrate serial interface communication protocol.
