Use original FT232RL
Support Mac, Linux, Android, WinCE, Windows 7/8/8.1/10...
Support 3 power supply modes: 5V external power supply; 3.3V external power supply; external power supply (requires 3.3V-5V)
With 3 LEDs: TXD LED, RXD LED, POWER LED
TXD, RXD, RTS#, CTS#: lead out with curved pin
Other functions PIN: reserved pad (distribution pin, row seat, can be plugged into or plugged into the user system; PIN spacing supports insertion into the universal board)
Instructions for use: (Take access to MCU as an example)
VCCIO: output 3.3V or 5V (module is powered by USB, jumper cap must be jumped to 3.3V or 5V)
GND: Connect to GND
TXD: Connect to MCU.RX (Signal flow direction: MCU.RX << FT232 << PC.TX)
RXD: Connect to MCU.TX (Signal flow direction: MCU.TX >> FT232 >> PC.RX)
RTS: Connect to MCU.CTS (Signal flow direction: MCU.CTS << FT232 << PC.RTS)
CTS: Connect to MCU.RTS (Signal flow direction: MCU.RTS >> FT232 >> PC.CTS)
Note: This module is USB to TTL level, do not directly connect to RS232 level, otherwise the module will be burned.
