After some wasted time with expensive PCB design errors, we've finally got a release candidate of the production version of the BlimpDuino board. It's version V431.
Changes from previous versions include:
--Square, rather than rectangular, so the IR detectors are all on the outside of the board (and thus free of interference) and evenly spaced for optimal sensing.
--Improved power supply, with lower profile and LiPo low-voltage cut-off (to protect the batteries)
--Vectoring servo now output on a digital pin (10) to use timer-based Arduino servo library
--Various layout tweaks to give more room for various connectors and the on/off switch
