Modified only the board holder upper part in order to mount the following:
- Raspberry Pi Zero W
- 2 battery stacked
- XT-60 connector for LiPo battery
- Power switch
- Raspberry Pi Camera
Inside the tank chassis a wired board with DCDC converters (Vin from Lipo batteries, Vout =5V for servo motors).
Needed to add an NTC to battery input to limit the inrush current to servo motors when battery is inserted, that caused DCDC explosion.
Needed to keep separated 5V of servo motors and for Raspberry Pi with 2 different batteries, otherwise problems of RaspPi reset when rotating the motors.
