Si4432 Wireless Data Transmission Module

The wireless data transmission module DT230 integrates a high-speed microcontroller and ADI's high-performance RF chip Si4432. It offers multiple channel options, and through the accompanying USB conversion board or online, it allows modification of various parameters such as serial port rate, transmission power, and RF rate. It supports frequencies of 433MHz, 470MHz, 868MHz, and 915MHz, with a maximum transmission power of 100mW (configurable). The receiving sensitivity is -113dBm@9600bps, and it uses GFSK modulation. It employs a UART/TTL interface, with optional RS232 and RS485.
