Bluetooth Module Small Version

Bluetooth Module Small Version


IoT Bluetooth Module based on CC2640 Texas Instrument

RC-CC2640-A is designed based on CC2640R2F128 Bluetooth Smart (Bluetooth 4.2 and Bluetooth 5.0) System-on-Chip, fully supports the single mode Bluetooth Low Energy operation.

The module provides the ability to either put your entire application into the integrated ARM Cortex M3 microcontroller, or use the module in Network Processor mode in conjunction with the microcontroller of your choice.
