MicroPeakUSB v2.0

The MicroPeak USB Interface v2.0 board contains a phototransistor, op-amp and serial-to-USB interface chip. It also includes a blue LED which blinks in time with the MicroPeak orange LED. This makes aligning the two boards by hand quite easy.

Here's a picture of the device in operation, with MicroPeak positioned to transmit data. The blue LED on the interface board is visible through the smaller hole in the front of the box.
