+- Pin Description
+
+Note: When only some pins are used, the wiring should be done in  descending order of row and column numbers. For example, when EC600M  uses a 2x2 matrix keyboard, the hardware uses pins 49, 51 and 48, 50.

+| -------- | ------------------------------------------------------------ |
