Universal converter module with USB - UART - RS232 output. It allows you to program Arduino boards (e.g. MultiWii) and other boards with RS232 / TTL input that do not have a USB connector on their board (like for ex. STM32). Specification: - Compatible with Win XP / Vista - PL2303 provides a convenient solution for connecting full duplex asynchronous RS232 serial device - PL2303 has drivers that simulate the traditional COM port on most operating systems allowing existing COM port based applications to easily communicate with the device. - compatible with USB 1.1 and 2.0 - speed up to 12Mbps - supply voltage: 5V - overload protection: 500mA - USB plug type A - 4pin connector (TX, RX, GND, 5V) - transmission speed: from 300bps to 1.5Mbps Color marking of leads: - Red + 5V - Black GND - White RXD - Green TXD It is enough to connect GND, TXD and RXD pins. Proper connection to the motherboard is very important - any other connection may damage your board electronics or the converter. Suitable for all boards with TTL / RS232 (TX / RX) input Drivers: http://www.mediafire.com/file/982x6iyk89v95dp/ProlificPL2303driverv3.3.2.102%25282008-24-09%2529Win8x64x86.7z/file https://elecena.pl/product/22605359/pl2303hx-usb-uart-rs232-converter-on-100cm-cable 2023-02-22 https://elecena.pl/product/22605359/pl2303hx-usb-uart-rs232-converter-on-100cm-cable 2025-10-29
