The x0x-heart is the heart of the x0xb0x, surgically extracted from the x0xb0x to be transplanted into your designs. The x0xb0x is a faithful replica of the Roland TB-303, complete with sequencer and DIN/MIDI/USB. The x0x-heart is just the analog section of the TB-303, replicated with SMT components, and made small enough to fit into a Eurorack modular format. It even has a Eurorack power header on it.
