PL2303 USB To UART (TTL) Communication Module (Type C)

Description: PL2303 USB To UART (TTL) Communication Module, Micro / Mini / Type A / Type C Connector.

• Adopts PL2303GS new version chip
• Supports windows XP/7/8/10/11/...
• 3x VCCIO power mode via jumper setting:
  • VCCIO - 5V: 5V output
  • VCCIO - 3.3V: 3.3V output
  • open the jumper: powered from target board (1.8V/2.5V/3.3V/5V)
• 3x LED indicators: TXD, RXD, PWR

Hardware connection:

• VCCIO ↔ 3.3V or 5V output (the module is powered from USB, and the onboard jumper should be shorted to 3.3V or 5V)
• GND ↔ GND
• TXD ↔ MCU.RX (signal direction: MCU.RX << PL2303 << PC.TX)
• RXD ↔ MCU.TX (signal direction: MCU.TX >> PL2303 >> PC.RX)

CAUTION: the module is compatible with TTL level ONLY, to avoiding any damage, please DON'T direct connect it to RS232 circuit.
