FT4232-4TTL 3.3V 2.5V 1.8V USB To 4-way TTL Module UART Serial Port Module Micro USB Interface

Overview 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 Features 1 VCC TX RX can all be switched to 5V 3 3 2 5V 1 8V2 The DC5 5 2 1 interface can provide high current to power external devices3 The four UARTs have TX RX indicator lights to show the status4 The four serial ports use the XH2 54 interface5 Board size 76 30mm6 Weight 14gInstructions for use Use a 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 to output The corresponding voltage 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 For a simple test you can short circuit TX RX and then use the host computer to send a message to see if there is any data echo Note When the module is powered by USB the load must not exceed 500mA otherwise the module or the computer USB may be overloaded and damaged If you only need to communicate you only need to connect the three wires TX RX GND When the mo
