2pcs 433MHz RF module 4438 chip original Long-Distance communication Receiver and Transmitter SPI IOT and 2pcs 433 MHz antenna
Product introduction
PM4438 wireless module uses SI4463 RF chip, high stability and high cost-effective. The module integrates the peripheral components required by the chip. The user only needs to control the internal registers of the chip through the SPI digital interface provided by the module to realize the functions of SI4463 parameter configuration and wireless data transmission and reception. The module has the characteristics of small size, high sensitivity, long transmission distance, high communication speed and small delay. Users can customize the module size, output power, frequency and other parameters according to their own requirements, or directly deploy the module to the user's PCB, improve the customer's product level and save costs.
Product Features
Micro power transmission, the maximum output is 100mW, and the transmit power can be controlled by setting. Working frequency band: 433/490MHz and other application-free frequency bands, the working frequency band can be customized according to user requirements. The receiving sensitivity is as high as -124dBm@1200bps. When the antenna height is 2 meters, it can reach 2000 meters without interference in open area.
