Balance Mainboard parts diagram: 1 bare PCB, 2 microcontroller, 3 power MOSFET, 4 gate driver IC, 5 current sensor, 6 connector, 7 board heatsink. 30 parts in 7 top-level items.
Balance Mainboard parts diagram. Numbers match the table below; each box is one top-level part or assembly with what it contains.
#PartQtyWhat 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 2× Balance and motor MCUs
3 Power MOSFET 12× Power MOSFET: a voltage-controlled semiconductor switch that turns high currents on and off at high speed in converters and motor drives.
4 Gate Driver IC 2× Integrated circuit that turns a logic-level control signal into the fast, high-current gate pulses needed to switch a MOSFET or IGBT.
5 Current Sensor 4× Hall-effect or shunt-based sensor that measures the current in a conductor and reports it to the controller.
6 Connector 8× 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.
7 Board Heatsink 1×
