c2a65d1e35 midnight edition, 1x2 layout
taking space of two ATTami (1800x900 mil) .
leaving much place for silkscreen.
power on the right, servos on the left
no VCC pins on shield.
bottom copper plate is no longer ground, its now V_BAT.

[zvi] changed the schematics. MIC5205 is in together with its capacitor C3.
The MIC5205 has two drawbacks:
  a. No guaranteed behavior for Vin < 5.5 V.  
  b. No guaranteed behavior regarding reverse leakage.
For applications with external supply greater than 5.5V there is no problem.
We will have to test the reverse current issue when operating on USB 5V without external supply.
We will have to test the dropout issue when operating on external supply lower than 5.5V.
Anyhow we will be able to switch back to the MIC5225 without changing the PCB.
