Description
TMB with Digispark Soft-Touch Footswitch for 125B Pedal Board Power Amplifier
The is a preamp board that can be sandwiched with a preexisting TPA3118 power amp module to make a pedal-board power amp in a 125B case.
There are 6 variants of this board in two categories: Volume-Only control; Treble-Middle-Bass control. Those two categories each have 3 different circuits for soft-touch footswitch control: Discrete circuitry; ATtiny chip; Digispark module.
The three different footswitch methods all behave identically, just implemented differently to suit the desires of the builder.
Full build documentation and the Arduino sketch files are here.
