Charge Controller 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 1× Single-chip microcontroller combining a processor core, flash memory, RAM, and peripherals such as timers, ADCs, and serial ports to run the device's control firmware.
3 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.
4 Firing Circuit 1× Gate pulse transformers
5 Voltage Sense Divider 1× Precision divider feeding scaled DC bus voltage to the regulator ADC.
6 Current Shunt 1× Calibrated 75 mV shunt measuring charger output current.
7 Hall Sensor 1× Battery current direction
