Package includes 4 DuPont wires.

This module supports 5V / 3.3V / 1.8V three-level voltage switching for VCC/TX/RX/RTS/CTS/DTR/DCD/RI/switch pins.

Module Features:
1. The FT232RL main control chip offers high speed and excellent stability.
2. Supports Windows XP/WIN7/WIN8/WIN10 32-bit systems.
3. Stable communication speed up to 3Mbps (three times that of 921600 bps).
4. The power VCC and signal levels (including flow control pins CTS/RTS/DTR/RI/DCD) can be freely switched between 5V/3.3V/1.8V, adapting to systems with different voltage requirements.
5. Integrated with three indicator LEDs: Power (blue), Receive (green), and Transmit (red).
6. On-board 500mA self-resetting fuse automatically trips in case of overcurrent or short circuit, effectively protecting the computer's safety.
7. Strong power supply capability, with a maximum output current of 500mA, capable of driving most microcontroller system boards.
8. Integrated protection diodes ensure the module is not damaged even if abnormal voltages occasionally occur on the signal lines.
9. The CTS/RTS/DSR/RI/DCD signal pins are accessible, facilitating hardware flow control.
10. Compact size and high integration; PCB dimensions are only 20*50mm, occupying the width of just one USB interface. Even with closely spaced USB ports, it does not interfere with plugging in other devices on the computer.

Pin Description:
1. 5V/3.3V/1.8V Select Pin: Use a jumper cap to select the output voltage. (Must be connected.)
2. TX/RX: Serial data pins (referring to the TX/RX of the module, corresponding to the RX/TX of external devices).
3. VCC/GND: Power/Ground (GND must be connected; VCC can be left unconnected if not needed).
4. Hardware flow control pins are reserved. As they are rarely used, pin headers are not soldered by default.
5. For shipping, the TX/RX pins are shorted with a jumper cap for functional testing. This cap can be removed during use.

Note:
The FT232 chip is domestically produced, and its EEPROM cannot be modified. As a download tool, this function is not required. If you have any special requirements, please review this information before placing your order. This will help avoid any delays in use. Thank you for your cooperation.
