Cytron Technologies UC00C User Manual
Cytron Technologies UC00C is a low-cost, easy-to-use USB to UART converter that enables communication between microcontrollers and PCs. It offers direct interface with 3.3V or 5V logic microcontrollers, is USB powered, and provides a 5V supply from the USB port. The UC00C is compatible with the Arduino bootloader and appears as a virtual COM port on Windows 7, 8, and 10. It features a MicroB USB socket, power and activity LEDs, a header socket for Arduino boards, and a selectable switch for 3.3V/5V UART interface.

1.0 INTRODUCTION
Serial communication is most popular interface between devices and this applies to microcontroller and computer. UART is one of those serial interfaces. Classically, most serial interface from microcontroller to computer is done through serial port (DB9) or sometime is called RS232. However, since computer serial port used RS232 protocol and microcontroller used TTL UART, a level shifter is needed between this interface. Recently, serial port of computer have been phase out, it has been replaced with USB. Of course most developer chooses USB to serial converter to obtain virtual serial port. The level shifter is still necessary for UART interface. Thus, Cytron decided to develop a USB to UART converter which offers USB plug and play, direct interface with microcontroller and it provide low current 5V supply from USB port. This is User’s Manual for UC00C .
