FT232RL serial port module USB to TTL serial port small board 5V 3.3V 1.8V level Download the burn line Driver download link: https://pan.baidu.com/s/1x9Zwpr35d-R0rPVFrg7cAw This module support 5 V / 3.3 V / 1.8 V three level switch, VCC/TX/RX/RTS/CTS/DTR/DCD/RI/switch

The module 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 disconnect in case of overcurrent/short circuit, effectively protect 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.
