As requested here’s the a vero layout for the OKKO Diablo Boost+ based on a schematic drawn by Kusi. I chose to divide the effect into two separate vero boards. If you only want to build the OKKO Diablo there’s a vero layout for that effect, but if you also want to build the Boost+ extension there’s a separate boost stage vero layout.
If you decide to build the full Diablo Boost+ effect wire the output of the main board to a second DPDT/3PDT switch that either bypasses or engages the Boost+ stage. Remember to also connect the A and B points on the main board and boost stage board together.
I just like to add I haven’t actually built this, so as of now it’s still unverified.
