The is a high-performance, FCC & IC certified and ETSI-compliant SOC module featuring Bluetooth� SMART technology that incorporates the Texas Instruments CC2541 transceiver chip in one of the industry's smallest package x 2.5 mm). The module incorporates two crystals, TPS62730 step-down converter and the required RF matching and filtering for regulatory compliance. The modules operate in the global unlicensed 2.4GHz ISM/SRD frequency band. These radio modules are ideal for achieving low power wireless connectivity without having to deal with extensive Protocol, RF design and regulatory compliance, allowing quick time to market. The modules are 100% RF-tested to provide consistent performance. The A2541R24C has an RoHS-compliant ENIG finish and is packaged in 27-piece matrix trays on 500-piece tape & reel for high-volume automated manufacturing.

Optional "No GND Plane" area shown for compatibility with PCB antenna model. See product User's Manual for detailed information.

Pin-out shown is for operation using the Emmoco firmware featuring Bluetooth� SMART technology. See TI CC2541 datasheet and A2541 User's Manual for detailed pin descriptions. Viewed from top side

Ground detail (corner) Where applicable: NC = "NO Connection" Pin is NOT connected internally. DNC = "Do Not Connect" Pin reserved for internal use, ensure mating footprint pads are isolated. GND = "Ground" Connect the maximum number possible (minimum one for proper operation). References in (parentheses) show native CC2541 pin function. Footprint (PWB) Ground detail (edge)

Caution! ESD sensitive device. Precautions should be used when handling the device in order to prevent permanent damage.
