I got my Explorer HAT Pro last week and built a small remote control “car”.
Parts:
- Raspberry Pi Model A+ with Coupé Royale Pibow
- Explorer HAT Pro
- 5V Voltage regulator
- Pololu Ball Caster (3/4 inch)
- Micro Metal Gearmotor Bracket Pair (extended)
- Micro Metal Gearmotor (95:1, if I remember correctly)
- Pololu Wheel 60x8mm Pair (maybe a 32x7mm would look better)
- 2 x 9V battery (wired in parallel)
- Wifi dongle
- Some jumper cables
