2.4G RF Transceiver Module DL-24D8 with TI CC2500 Chip
Product Description
2.4G RF Transceiver Module DL-24D8 with CC2500 Chip Design
Module introduction
Designed base on TI-Chipcon's CC2500 wireless transceiver chip, DL-24D8 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 transmission rate up to 500Kbps, output power through register configuration range from -30dbm to +1dbm.
This 2.4GHz RF Module integrates all RF related functions. You can easily develop wireless products with stable performance and high reliability directly, without in-depth understanding of RF circuit design, which will extremely shorten the development cycle.
There are 2 interface modes (SMD and DIP) been 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 the requirements of low-power system by combining with low-power MCU.
