Control Board parts and their functions
9 top-level parts · 19 parts in total · full bill of materials below
| # | Part | Qty | What it does |
|---|---|---|---|
| 1 | Bare PCB | 1× | Unpopulated printed circuit board: copper traces etched on an FR-4 glass-epoxy laminate that carry current between the components later soldered to it. |
| 2 | Microcontroller | 1× | balance + motor control |
| 3 | IMU Module 3 parts | 1× | Gyro/accelerometer sensing pitch for the balance loop. |
| 4 | Power MOSFET | 6× | three-phase inverter low-current |
| 5 | IGBT Power Module | 1× | high-current phase switching |
| 6 | Hall Sensor | 1× | board-side current sense |
| 7 | SMD Passive (R/C/L) | 1× | Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board. |
| 8 | Heatsink | 1× | Aluminium heatsink bonded to the inverter switches. |
| 9 | Connector | 4× | Mating plug-and-socket pair that joins two lengths of wiring or a cable to a board so a circuit can be assembled, serviced, and separated without soldering. |
