Simple USB interface
The simple USB interface from DAGU provides a simple solution to
programming projects built on a breadboard. By plugging into the breadboard
vertically very little space is taken up making it ideal for use with small
breadboards. This interface works with Arduino compatible processors.
1. VCC +5V from the USB cable (500mA maximum).
2. RST Used to reset a processor prior to uploading a program (DTR).
3. RXD Data in.
4. TXD Data out.
5. GND Ground pin (0V).
The CP2102 USB interface IC is used on this board. The latest drivers for Windows, Mac and Linux can be downloaded from here:
Once the drivers have been installed the USB interface will appear on your
computer as a virtual serial com port.
