PCBWay Wireless Module with SI24R1 RF Communication Wireless Module for Data Transmission
Introduction:
The PCBWay Si24R1 module is a high-performance 2.4GHz wireless transceiver IC designed with a 2.4G wireless transmission module, employing GFSK/FSK digital modulation and demodulation technology. It operates within the internationally recognized ISM frequency band of 2400-2525MHz, offering 126 1MHz bandwidth channels. It supports three data rates: 2Mbps, 1Mbps, and 250Kbps. The Si24R1 integrates all RF protocol-related high-speed signal processing elements, such as automatic retransmission of lost data packets and automatic generation of response signals. The module's SPI interface can be connected to a microcontroller's hardware SPI port or simulated using the microcontroller's I/O port. It includes a FIFO for interfacing with various high and low-speed microprocessors, facilitating use with low-cost microcontrollers. The module utilizes a built-in PCB antenna design, achieving a test distance of approximately 50 meters for a transmission of 10 bytes of data at a rate of 1Mbps.
