Version 1.0

Version 1 had some design flaws, however, it was more than enough to build the "simple" wand for controlling the dresses. Design can be found on OSHPark - Problems in this design included:

• Extra (un-needed) battery pins for the LEDs (unused)
• Buttons pulled to 3V3 instead of GND
• Button padds WAY to small
• Wrong ports used for buttons (made the SD card reader impossible)
• Not enough GNDs and 3v3s for jjdb210 to be happy.

Version 2.0

Version 2 was a fix for the "master" wand... primarly to make it so we could make use of SPI. Bugs from Version 1.0 were fixed. Found on Oshpark
