The USB to TTL Serial Port Board, featuring the FT232RL Serial Port Module, facilitates easy communication between a computer and microcontrollers. With selectable voltage levels (5V/3.3V/1.8V), it supports diverse applications. Ideal for downloading and recording data, this board ensures efficient data transfer, making it an essential tool for electronics enthusiasts and developers alike.

Features:

1. Original FT232RL main control chip, fast speed, and good stability.
2. Support Windows XP/WIN7/WIN8/WIN10 32/64-bit system.
3. Stable speed up to 3Mbps (3 times 921600).
4. The power supply VCC and signal level (including CTS/RTS/DTR/RI/DCD) can be freely switched at 5V/ 3.3v / 1.8v to adapt to different voltage systems.
5. Integrated power supply (blue), receiving (green), and sending (red) three indicator lights.
6. 500mA self-recovery fuse on board, automatically disconnects in case of overcurrent/short circuit, effectively protecting computer safety.
7. Strong power supply capacity, up to 500mA current output, can drive most of the single-chip microcomputer system board.
8. Integrated protection diode, signal line occasionally abnormal voltage will not damage the module.
9. Lead out CTS/RTS/DSR/RI/DCD signal pins, which can facilitate hardware flow control.
10. Small size and high integration, PCB is only 20*50mm and only occupies the width of one USB port. Even if the USB port is very close to the computer, it will not affect the insertion of other devices.

Pin description
1. 5v / 3.3v / 1.8v select pin: switch short circuit cap to select output voltage. (must be connected)

2. TX/RX: serial data pin (refers to the TX/RX of the module, corresponding to the RX/TX of the external device)

3. VCC/GND: power/ground (GND must be connected, VCC can be suspended)

Hardware flow control pin reserved, because it is rarely used, so the default row pin is not welded

TX/RX pin short circuit cap shall be connected directly when shipping, for testing function, and it can be removed when using.
