How to connect the board?
The USB UART 2 additional board can be easily connected to PC via a USB MINIB connector CN1. Connection with
the microcontroller is established via 1x6 connector CN2 and 1x9 connector CN3. 1x6 connectors enable access to the
microcontroller pins that are used for serial UART communication. A 1x9 connector CN3 is connected to the pins of the
MCP2200 chip supplied on the additiona board.
USB UART 2
The USB UART 2 additional board is used to connect a PC and the UART module built into the microcontroller.
Key features:
- Data transfer via UART;
- 5V DC power supply voltage;
- Low power consumption; etc.
