@Hippie_Moose welcome to the Blokas community!
FWIW, I also built a custom MIDI pedalboard (not PedalinoMini) to use with MODEP. I chose a Raspberry Pi Pico W as my controller and decided to connect the pedalboard through a USB cable. Being able to connect via bluetooth or wifi is cool but I wanted something that I could just turn on and not have to fuss with wireless. In my case, the MIDI controller is mounted to the same pedalboard just a few inches away so using wireless is not really required in my case.
