tornado/cpu/: new version of the CPU board (WIP)
...
Differences:
- a bit smaller, 42.25 x 22.5 mm. The old version was 43.75 x 25.25 mm
- NXP LPC1112FHN33/202 MCU (Cortex-M0)
- step-down converter for the 3.3 V supply
- all-digital 3D acceleration sensor
- one local LED
- push-pull card holder
Note that the interface to the LED modules has changed as well. New
features:
- high supply voltage
- optional sharing of regulator
- double ground

all 64 of them, we now show a filling/emptying bar. The update speed is
high enough that rotation results in about a quarter-circle pattern.
