GB254X is a Texas Instruments TI uses Bluetooth 4.0 CC2540 or CC2541 as the core processor, high-performance, ultra-low power (Bluetooth Low Energy) RF transceiver system module, follow a low-power Bluetooth protocol, suitable for single-mode Bluetooth low energy application.
CC254x integrates a 1Mbps GFSK RF transceiver and use 8051MCU a rich peripheral cores,
providing significantly better than competing products, transmission coverage area,
it has a smaller package within the current size of the industry (13.7x 17.4 x 1.9 mm).
