Arduino Synth plus Delay

The PCBs arrived on time and they were perfect! The support people helped to solve some issues I had and I’m really happy with the result. I’ll order here again, thanks! This PCBs will help me to save tons of time creating the synthesisers I create based on arduino. I can now fit all the components, including the arduino board and the inputs and outputs in one single place. Really looking forward to develop them! Also color and text are perfect.
