Yet, serial port on computer has been phased out and replaced by USB. Therefore, Cytron decided to develop a USB to UART converter which offers USB plug and play, direct interface with a microcontroller and it provides 5VDC supply from the USB port. Rev3.0 added 3.3V voltage regulator (max output current 500mA), and a slide switch to choose 5V or 3.3V for logic and Vsel level. It also utilises the commonly used USB microB socket, grab the USB microB cable if you do not have one yet.

Features
