This module supports three levels of level switching of 5V/3.3V/1.8V. VCC/TX/RX/RTS/CTS/DTR/DCD/RI/can be switched

Module characteristics
1. Original FT232RL main control chip, fast speed and good stability.
2. Support Windows XP/Win7/Win8/Win10 32/64 -bit system.
3. The stable speed can be 3Mbps (3 times the 921600).
4. Power VCC and signal levels (including the flow control tube foot CTS/RTS/DTR/RI/DCD) can be freely switched at 5V/3.3V/1.8V to adapt to a system of different voltage.
5. Integrated power supply (blue), receiving (green), sending (red) three indicators.
6. 500mA self -recovery fuse, automatically disconnect when flowing/short circuit, effectively protecting computer security.
7. Strong power supply capacity, maximum output 500mA current, can drive most single -chip microcomputer system boards.
8. Integrated the protection diode. Occasionally abnormal voltage appears in the signal cable and does not damage the module.
9. Lead the CTS/RTS/DSR/RI/DCD signal tube foot, which can easily perform hardware flow control.
10. Small volume and high integration. PCB is only 20*50mm. It only takes up the width of one USB interface. Even the USB port distance is very tight on the computer without affecting other devices insertion.
Tube explanation

1.5V/3.3V/1.8V Select pins: Switch the short -circuit cap to select the output voltage.(Must be connected)

2.TX/RX: serial data tube foot (referring to the TX/RX of the module, the RX/TX corresponding to the external device)

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

The hardware flow control tube foot is reserved, because it is rarely used, so the default is not welded

During the delivery, the TX/RX tube feet short -circuit cap is directly connected to test functions, which can be removed when used.
