USB to I2C Debug Board




This is a serial to USB board that works with I2C transceivers. It comes with a PIC18F26J50 preloaded with code that allows the transceivers to act as pass through serial devices. When powered up, the LEDs will blink to indicate an operational USB connection. You will need to use Microchip VCP drivers, so that your USB connection comes up as a COM port. Then all you need to do is use a terminal program to communicate with the I2C device.
