FT232RL / FT232 USB UART Board is the FT232 USB to TTL USB PORT, FT232 USB Module to serial adapter.
FT232 USB Module FT232RL to Serial Port FT232 USB UART Board.
Supports three power modes: 5V external power supply; 3.3V external power supply; externally powered (requires 3.3V-5V)
Comes with 3 LED: TXD LED; RXD LED; POWER LED;
MCU communicates with the PC (using the UART protocol software, hardware based USB interface).
The main resources:
FT232, USB type A interfaces, UART interfaces, select the interface mode power supply.
Directions for use: (here, in order to access to the MCU, for example, to explain how the each PIN connection), VCCIO: 3.3 V to 5 V input (module by an external power supply, should be the jumper cap jumped) or output of 3.3 V or 5 V (module by the USB power supply, should be the jumper cap jumped to 3.3 V or 5 V)
GND: connect GND
TXD: by MCU. RX (signal flow: MCU. RX < < FT232 < < PC. TX)
, RXD: by MCU. TX (signal flow: MCU. TX > > FT232 > > PC. The RX)
RTS# : by MCU. CTS (signal flow: MCU. CTS < < FT232 < < PC. The RTS)
CTS# : by MCU. The RTS (signal flow: MCU. The RTS > > FT232 > > PC. CTS)
Special tips: • support Windows.
• TXD, RXD, RTS#, CTS# : applying bending row needles.
, the rest of the PIN: no welding row needle, row, row needle, row seat, but distribution can be made of user customization, on or under the access to the user's system.
