=== Rev1 Issues ===<br />
<br />
* <s>GPS LED connected to ground instead of 3.3V</s> (Fixed 16/11/09)<br />
* <s>GPS backup battery pin need to always be connected to something, add option to connect to 3.3V</s> (Fixed 16/11/09)<br />
* <s>GPS REGEN pin needs to be connected to 3.3V</s> (Fixed 16/11/09)<br />
* <s>Make the pyro connector holes a bit bigger to fit the larger diameter pins of the cool orange connectors</s> (Fixed 16/11/09)<br />
* The current switch really really sucks. (Better quality drop-in replacement: http://parts.digikey.com/1/parts/1211254-switch-slide-1pdt-6vdc-0-3a-smt-js102011saqn.html)<br />
* Reverse supply protection diode<br />
* <s>Consider moving to a switch mode supply, although for operation from a LiPo its not to bad to use a linear. A buck-boost would squeeze some more juice out if its not too much faff.</s><br />
* GPS antenna package is a but too wide.</div>EllieClifford
