Serial communication is the most popular and commonly used interface between devices and it applies to microcontroller and computer too. UART is one of those serial interfaces. Classically, most of serial interface between a microcontroller and a computer is through serial port (DB9). Computer serial port uses RS232 protocol and microcontroller uses TTL (Transistor Transistor Logic) UART, a level shifter is needed between these interfaces.
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.
Note:UC00A is compatible with Window XP, Vista, 8, 10, Win7 (32-bit and 64-bit) and it appears as Virtual COM port on the computer.
Uses the market leader in USB to Serial IC, FTDI FT232RL
Easy, plug and use USB to UART converter
Aiming development between computer and microcontroller, 3.3V or 5V logic
USB powered, no external source is required
5V from USB port is available for the user, via Vsel
Configurable logic level of 3.3V or 5V for UART interface
CTS, RTS, DTR and DSR are extended out to standard header pin solderable PCB pads (side)
Plug and Play, the driver is needed for 1st time user only.
Rev3.0 have 6 ways header socket for bootloading code into Arduino compatible board:
