High-performance 2.4G Transceiver Module with TI Chip

Module introduction

Designed base on TI-Chipcon's CC2500 wireless transceiver chip, DL-24A is a compact,cost-effective, remote wireless transceiver module, which is widely used in smart home, toy aeromodelling and close-range data transmission control fields. Sensitivity up to -98dbm,maximum transfer rate up to 500Kbps, output power through register configuration range from -30dbm to +1dbm.

This wireless module integrates all radio frequency related functions, you can easily develop wireless products with stable performance and high reliability directly, which will extremely shorten the development cycle without in-depth understanding of RF circuit design. SMD and DIP interface modes are adopted, but manual welding is required due to different thermal expansion coefficient of the black glue and the binding wire inside.

The small size of the module is convenient for portable products, and it can well meet therequirements of low-power system by combining with low-power MCU.
