Waveshare PL2303 USB UART Board (type A)

The PL2303 is a USB-to-Serial Bridge Controller, offering both low cost and high performance. It serves as a convenient solution for connecting RS-232-like full-duplex asynchronous serial devices to any Universal Serial Bus (USB) capable host.

Its highly compatible drivers can emulate traditional COM ports on most operating systems, enabling seamless migration of existing applications based on COM ports to become USB-ready.

Designed with mobile and embedded solutions in mind, the PL2303 features a compact footprint suitable for integration into various connectors and handheld devices. Its minimal power consumption in both operating and suspend modes makes it ideal for bus-powered operation, with ample power remaining for connected devices.

Pin connections of FT232 USB UART Board:

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

This breakout also allows you to connect the TX/RX pins of your favorite microcontroller or serial application to the RX/TX pins of the breakout, creating a simple serial cable replacement.

Package Includes:

1 x PL2303 USB UART Board (type A)

1 x 4-pin custom connector jumper wire
