+# MicroPeak USB Interface #
+
+The MicroPeak USB Interface board provides a way to capture flight
+logs over a USB connection to a computer running Linux, Mac OS or
+Windows.
+
+<a href="v1.0/MicroPeakUSB.jpg"><img src="v1.0/MicroPeakUSB-640.jpg"></a>
+
+## MicroPeak Data ##
+
+ * Stored in on-chip 512B eeprom
+ * Records raw barometer readings every 192ms
+ * Enough storage for 48 seconds
+
+No changes are needed to the MicroPeak hardware, but new firmware that
+includes the data download feature is necessary to use the MicroPeak
+USB Interface.
+
+## MicroPeak Interface ##
+
+MicroPeak transmits the entire flight log via the LED just after
+reporting the last flight altitude at power up. The data are
+transmitted in regular serial format at 9600 baud.
+
+The MicroPeak USB 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.
+
+## MicroPeak Application ##
+
+Java application that runs on Windows, Mac OS X and Windows.
+Captures and saves data, provides plots and statistics.

+
+## Developer View ##
+
+Here's a close-up view of the hardware
+
+ * Hardware Features
+ * ROHM RPM-075PT Phototransistor
+ * Peak sensitivity matches MicroPeak LED color
+ * [ST Micro TSV521](http://www.st.com/internet/analog/product/251123.jsp) CMOS op-amp
+ * Low power
+ * [FTDI FT230](http://www.ftdichip.com/Products/ICs/FT230X.html) Serial to USB adapter
+ * Drivers available for Linux, Mac OS X and Windows.
+
+ * Tools Used
+ * [gEDA](http://www.gpleda.org/) for schematic capture and PCB layout
+
+ * Licenses
+ * The hardware is licensed under the [TAPR](http://www.tapr.org) [Open Hardware License](http://www.tapr.org/ohl.html)
