PL2303 USB UART Module (USB-A)

This is a USB to UART conversion board featuring a PL2303GS USB to serial bridge chip, RS/TX/Power indication LEDS and a USB-A connector. We also stock a version with a Micro-USB connector and a USB-C connector. Note: the module is compatible with TTL level only, to avoid damage please do not directly connect to an RS232 circuit. Features

* PL2303GS onboard

* Supports windows 7/8/8.1/10/11

* 3 VCCIO power mode via jumper setting:

* VCCIO - 5V: 5V output

* VCCIO - 3.3V: 3.3V output

* Open jumper: powered from target board (1.8V/2.5V/3.3V/5V)

* 3 LED indicators: TXD, RXD and POWER

Pinout When working with an MCU such as the ATMEGA 328:

* VCCIO ↔ 3.3V or 5V output (the module is powered from USB, 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)

Package Contents

* 1x PL2303 USB UART Board (type A) V2

* 1x 4-pin custom jumper cable (female to female)
