Small Form Factor Bluetooth Low Energy (BLE) Reference Design

Texas Instruments

This design showcases the CC254x family of Bluetooth® low energy (BLE) wireless microcontrollers (MCUs) + a meandered F antenna in a compact form factor that can be soldered to an existing PCB. This reference design provides access to all I/Os of the BLE wireless MCU allowing the evaluation of BLE connectivity in existing systems. This design is compatible with Texas Instrumentss royalty-free BLE stack that include example applications for faster evaluation.
