PL2303-based Solution
The module is built on the new PL2303GS chip, ensuring reliable and stable data transfer between the computer's USB interface and the microcontroller's UART interface.
Connecting to a Microcontroller
Example of connecting the PL2303 USB UART Board (Type A) module to an MCU:
- VCCIO ↔ 3.3V or 5V (module powered by USB; jumper on board set 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 ONLY compatible with TTL levels. To avoid damage, DO NOT connect it directly to RS232 circuits.
