DollaTek FT4232-4TTL USB to 4 Way TTL Module FT4232HL UART Serial Port Module DC 5V 3.3V 2.5V 1.8V 4 Channel XH2.54 Interface Board

• The excellent performance of FT4232HL is very suitable for high-demand industrial occasions.
• It realizes simultaneous communication with a single USB to expand 4 UART serial ports, independent of each other, and does not affect each other. The computer displays 4 COM ports and provides a maximum communication rate of 12Mbps.
• VCC, TX, RX can all be switched to 5V/3.3V/2.5V/1.8V.
• The DC5.5-2.1 interface can provide high current to power external devices.The four UARTs have TX/RX indicators to show the status.
• The four serial ports use XH2.54 interface.

Description: The excellent performance of FT4232HL is very suitable for high-demand industrial occasions. It realizes simultaneous communication with a single USB to expand 4 UART serial ports, independent of each other, and does not affect each other. The computer displays 4 COM ports and provides a maximum communication rate of 12Mbps. Instructions for use 1. Use the USB cable to connect the computer to the MICROUSB interface on the board. After the computer is installed with the driver, you can see that 4 COM ports appear. Use the short-circuit cap to select the desired VCC/TX/RX voltage on the TTL power selection interface. The corresponding voltage can be output. 2. The smallest value of the COM port corresponds to the first TTL interface, and the largest value corresponds to the fourth TTL interface (the value of the COM port is not fixed). 3. For 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. Package include: 1 x module
