***NOTE：
****1. X9C104S is a low-power CMOS device, be careful that static electricity will damage the device, especially after replacement, it must be cooled to room temperature before powering on.

****2.Module debugging note:
The digital multimeter usually "displays abnormally" when measuring the resistance terminal value. This is because of the special internal structure of the digital potentiometer, and the working state of the potentiometer needs to be measured by the voltage division method.
Use DC 5V voltage to connect to VH and VL terminals, and then use the voltage range of the multimeter to measure the voltage of the VL port and VW port. After the potentiometer works, change the resistance value, and the voltage measured by the multimeter changes accordingly, which means it is working normally.

************************************************

Parameter:
Power supply voltage: 3V-5V.
Chip: X9C104S.
PCB board size: 2.7*1.3CM.
100K range potentiometer.
Potentiometer center taps slide at 0-100k for a total of 100 (potentiometer taps typical impedance 40 ohms).
The VL and VH digital potentiometer slip varistor ports correspond to the low and high side, allowing the input voltage range to be -5V to +5V.
