Four brushed-motor outputs, sixteen servo outputs and the Pi-connected MPU6500. This list is also available offline in the Mini dashboard under Debug → Parts list.
| Quantity | Part | Selection |
|---|---|---|
| 1 | Raspberry Pi 5 | 4 GB is sufficient |
| 1 | microSD card | 32 GB or larger, A2 recommended |
| 1 | Active cooler | Argon THRML 30 mm |
| 2 | Dual H-bridge motor driver | GODIYMODULES DC 3–18 V; two motors per board |
| 1 | PCA9685 servo controller | AITRIP PCA9685, 0x40, all address pads open; 16 servo outputs |
| 1 | MPU6500 IMU | Reference module; same independent Pi I²C bus |
| 1 assortment | Self-tapping screws | Fasvicna M1.7–M3, 750 pieces |
| Up to 4 | Brushed 12 V motors | goBILDA Yellow Jacket, or another suitable 12 V brushed motor |
| Up to 4 | Motor bullet leads | goBILDA MH-FC to bare wire |
| Up to 16 | Servos | Same servo choices and regulated power requirements as the full module |
Use four M2.3 × 5 mm self-tapping screws for the Pi. Use M3 × 5 mm for the two motor-driver boards, PCA9685 and IMU, one per mounting hole. The Mini enclosure and its corner screw count must follow its final CAD; the full enclosure's 22-M3-screw total is not a Mini specification.
Use the same power module: 12 V battery, XT30 leads, cutoff switch, Pi USB-C converter, regulated 5 V / 5 A servo converter and electronics box. The two driver boards each share a 10 A budget between their two motor outputs. Servo current remains limited by the same 5 A converter. Keep motor and servo power away from Pi header power pins.
Use the same wire, connectors and setup tools. Mini has no Drivers 3 or 4 and no motor channels 5–8. Mini enclosure CAD is not included; the power-box CAD is still available. See the Mini pinout before connecting the robot.
