915 Generation Serial Port Module UART USB to 4 Way TTL 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 VCCTXRX 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 TXRX and then use the host computer to send information to see if there is any data echo
VCC TXRX can all be switched to 5V3325V18V
The DC55-21 interface can provide high current to power external devices

All four UARTs have TXRX indicator to show the status
The four serial ports use XH254 interface
