DAB2140 Multimode VCF prototyping module
Super sounding, super configurable, super fun, make all manner of filters, phasers and whatnot without doing any SMD soldering.
The DAB2140 has an SSI2140 pre-soldered along with two decoupling caps in an optimal position and some presoldered headers for plug and play action (once you've laid out the rest of your circuit). This means that this cutting edge update to a classic synth chip can be used on breadboard, stripboard, veroboard or your own PCB's.
Full details here for DIY synth fun in the SSI2140 datasheet.
