Wireless Transceiver Module Wireless Module Serial Port 433Mhz SI4438/SI4463

Features:
At the transparent transmission mode, baud rate, and wireless communication channel must be set to the same. The factory default settings are FU3, 9600bps (8-bit data, no parity, 1 stop bit), and CH100 (443MHz). This mode can automatically adjust the air baud rate according to the serial port baud rate, and the communication distance is the farthest at low baud rate.When using, it is generally not limited to the number of bytes sent continuously to the serial port of the module. However, in view of environmental interference and other factors, when a large amount of data is continuously transmitted at a time, some bytes may be lost. Therefore, the host computer should have mechanisms such as answering and resending to avoid information loss.
