The board showed above has the following IO set
- amplifier: GPIO21
- key2: GPIO13, key3: GPIO19, key4: GPIO23, key5: GPIO18, key6: GPIO5 (to be confirmed with dipswitches)
- key2: GPIO13, key3: GPIO19, key4: GPIO23, key5: GPIO18, key6: GPIO5 (to be confirmed with dip switches)
- key1: not sure, something with GPIO36
- jack insertion: GPIO39 (inserted low)
- LED: GPIO22 (active low)
(note that GPIO need pullups)
So a possible config would be
- set_GPIO: 21=amp,22=green:0,39=jack:0
- a button mapping:
```
