1) Wide voltage (3V-5V) power supply. The chip is X9C103S/X9C503S; PCB board size: 2.7*1.3CM
2) 10K/50K full-scale potentiometer.
3) The middle tap of the potentiometer slides between 0-10k (X9C103S)/0-50K (X9C503S) for a total of 100 levels (the typical impedance of the potentiometer sliding end is 40 ohms)
4) The VL and VH ports of the digital potentiometer correspond to the low and high ends of the sliding resistor respectively, and the input voltage range is allowed to be -5V to +5V.
