This product is an industrial USB to TTL converter. It uses original FT232RL, built-in self-healing fuse, ESD and 10 protection diode circuit. Small and compact. Using the original FT232RL chip, providing better stability and compatibility, and easy to achieve industrial high-performance communication between computers and TTL devices
Support Win7 / 8 / 8.1 / 10, MAC, Linux, Android, Win ce and other systems

Pin Description
5V: 5V supply voltage
VCC: output 3.3V or 5V (module is powered by USB, switch must be switched to 3.3V or 5V)
GND: Connected to GND
TXD: connect to MCU RX (signal flow direction: mcu.rx RXD: connect to MCU TX (signal flow direction: MCU. TX > ft232 > > pc.rx)
RTS:Connect to MCU CTS(Signal flow direction: MCU. CTS CT:Connect to MCU RTS(Signal flow direction: MCU. RTS > ft232 > pc.cts)
PWR: Power indicator, connected to USB, red light when voltage is detected
TXD: Transmit indicator, red light when sending data from USB port
RXD: Receive indicator, red light when sending data from device interface
