MakerFocus 433Mhz SI4463 Wireless Transceiver Module Serial Port 1200M with Antenna

Description:The GT-38 wireless serial communication module is a new generation of multi-channel embedded wireless data transmission module. There are a PCB antenna holder ANT1 and a spring antenna welding hole ANT2 on the module, you can select one of the antennas according to your requirement.Four modes FU1, FU2, FU3, and FU4 have an average operating current of 3.6mA, 80μA, 16mA, and 16mA in idle state, and the maximum operating current is 100mA (full power emission state).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 i
