these SAMxxxx chips are a big family, found in numerous musical devices. With embedded keyboard and button decoders, led drivers, synth engines, effects, sampler capabilities with external storage… they are highly capable ! conceived by a french company called Dream.

The sam2695 has cropped up a couple of times before

so with this item you have a synth?
how to power it and how to control it?

Well to test mine I hooked up a grove connector and connected pin 1 to gnd, pin 2 to +5v and tied 3 & 4 together. Then I just plugged in a controller to the Midi in and some headphones to the audio out.

you can find the specs here to talk to it with midi:
