Product characteristics:

• the original FT232BL industrial chip is adopted, and the external EEPRON(93C46) is more stable
• support for Windows 10
• support 3 power supply modes: 5v external power supply; V external power supply; External power supply (requires 3.3v-5v)
• with 3 LED:TXD LED, RXD LED, POWER LED
• GND, RXD, TXD, 3V3, 5V: use curved pin to lead
• PIN for other functions: reserved pad CTS, RTS
• with 500MA self-restoring fuse reverse burn

use cases:

• upgrade RS-232 traditional device to USB
• USB to RS-232 serial adapter

instructions: (take access to MCU as an example)

• GND: Pick up GND
• RXD: Connect to MCU.TX (signal flow: MCU.TX >> FT232 >> PC.RX)
• TXD: Connect to MCU.RX (signal flow: MCU.RX << FT232 << PC.TX)
• 3V3/5V: output 3.3V or 5V (the module is powered by USB, and the jumper cap must jump to 3.3V or 5V)
• RTS: Connect to MCU.CTS (signal flow: MCU.CTS << FT232 << PC.RTS)
• CTS: Connect to MCU.RTS (signal flow: MCU.RTS >> FT232 >> PC.CTS)
