DL-Si24R1-A Wireless Module was designed based on Si24R1 RF transceiver chip from CSM-IC. It is an industrial grade 2.4G wireless module with PCB on board antenna, which is SMD packaging and compact in size. Its highest transmission rate can reach 2Mbps, while the maximum transmission power is about 7dbm. 

This 2.4G Wireless Transceiver Module uses SPI interface, and adopts 16MHz crystal oscillator (high precision, high temperature stability), which is really an ideal product for various IoT applications, such as Smart Grid, Smart Home, Toy Aeromodelling, Medical Equipment, Sweeper Robot, Wireless Keyboard and Mouse, Wireless Remote Control, Active RFID, NFC, Wireless Sensor Nodes for Low power Ad Hoc Networks, etc. 

This high-performance RF module has integrated all radiofrequency related functions, and 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.

This wireless module adopts stamp edge and half hole interface design, which can not only meet your SMT application, but also can realize transverse and longitudinal welding through pin header arrangement. 


1.  Since DL-Si24R1-A is a pure RF transceiver module, MCU drivers or special SPI debugging tools are required.

2.  DL-Si24R1-A 2.4G RF module is compatible with nRF24L01 RF modules, it is PIN to PIN with our DL-24N Wireless module, and also pin to pin with NF-03 RF module of Ai-Thinker.
