1 PCS USB to 4 Way TTL Module Serial Port Module FT4232 Chip DC 5V Converter Board for Equipment
Use a USB cable to connect the computer to the MICRO-USB interface on the board. After the driver is installed on the computer, you can see 4 COM ports appear. Use the short-circuit cap to select the desired VCC/TX/RX voltage on the TTL power selection interface to output corresponding voltage.
The COM port with the smallest value corresponds to the first TTL interface, and the one with the largest value corresponds to the fourth TTL interface (the value of the COM port is not fixed).
For a simple test, you can short-circuit TX/RX, and then use the host computer to send information to see if there is any data echo.
VCC, TX,RX can all be switched to 5V/3.3/2.5V/1.8V
The DC5.5-2.1 interface can provide high current to power external devices
All four UARTs have TX/RX indicator to show the status
The four serial ports use XH2.54 interface
