MicroPeakUSB 1.0

MicroPeakUSB is an optical to USB interface board used to extract the barometric altitude profile from a MicroPeak board after flight. 

MicroPeak transmits the entire flight log via the LED just after reporting the last flight altitude at power up. The data burst is transmitted in a simple serial format at 9600 baud.  The MicroPeakUSB Interface 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. 

The associated MicroPeak application written in Java runs on Windows, Mac OS X and Linux.  It captures and saves the flight data, then produces plots and statistics.
