The FX Development Board is an open source, audio electronics prototyping environment combining solderless breadboards with interfacing peripherals and a multi-rail power supply.
Its purpose is to aid in the prototyping and development of electronic guitar effects, audio synthesizers, and preamplifiers. Although the project has been geared towards audio designers, due to the generic nature of its integrated breadboards and power supplies, the board can be used for all kinds of electronic prototyping.
