On the Amp Hour you mention you wanted to make a last minute hardware change (albeit fairly minor), but was faced with the fact that 2000 boards had already been printed, and a cost that could not be absorbed. For this reason you were going to hold back, and maybe amend the board in a subsequent board spin. Are you planning to do this between the first Dec batch, and the April batch, using the delay as a chance to make the change? On the same note, what happens if/when there is a hardware change, and there are potentially different board revisions, with regards to firmware updates. Will updates need to be board revision specific?
