Syma X1 board replacement

The new Syma X1 board was fully loaded. It weighed 5.6g. The old Syma X1 board was 5.3g. The original board obviously wasn't optimized for size. The new board also has a much more powerful CPU & a full IMU. The Ladybird board was 2.7g, of course.

Test ran a motor to 1A. The MOSFETs do indeed need 5V to turn on. The mane unknowns are if the high current is going to interfere with the CPU, if the MOSFETS are going to blow, if the charge pump can bias all 4 MOSFETs, if the voltage regulator can power it at the required clockspeed.

Anyways, discovered ganging 4 GPIOs improves the video overlay. Still not as good as a multiplexer, but probably a better deal for the size & the application.
