When we use the single-chip microcomputer, sometimes we need more then one button module.

In general, we use a digital port to connect one button module. When multiple buttons are required, multiple digital ports are required, so that we would waste the source of single-chip microcomputer IO port.

So we specially design this module. It only need an analog port of single-chip microcomputer to show the function of five button module.

To conveniently mount the module on any other devices, it comes with 4 fixing holes of 3mm diameter.

Special Note:

When the supply voltage is different, the analog value corresponding to the same button on the module is different.

When using, we can’t press the multiple buttons in the same time; if you did, analog value read by the signal pin of the module is the minimum analog value corresponding to the multiple button.
