Logic Mainboard parts diagram: 1 bare PCB, 2 microcontroller, 3 IMU (6-axis), 4 phase current sensor, 5 pressure sensor, 6 SMD passive (R/C/L), 7 LED driver. 188 parts in 7 top-level items. — Logic Mainboard parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.

#	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×	Real-time balance/motor MCU
3	IMU (6-axis)	1×	6-axis gyro + accelerometer
4	Phase Current Sensor	3×	Per-phase shunts
5	Pressure Sensor	1×	Pedal/lean load sense
6	SMD Passive (R/C/L)	180×	Surface-mount resistors, capacitors, and inductors, typically in 0402 to 1206 packages, that set voltages, filter noise, and time signals on a circuit board.
7	LED Driver	1×	Lighting driver
