I bought half a dozen from Belton some weeks ago. They were kind enough to include a fully populated demo PCB with my order. So far I've designed 3 projects using the Belton ABE-FX, a Eurorack module, a MU format module, and the pedal you see above. It's pretty straightforward to design with, and sounds awesome. You can see the Euro and MU modules on my website. 100pcs Belton ABE-FX arriving with me tomorrow, and I have a bulk shipment of the PCB for the pedal version arriving next week, which will be added to my website over the weekend.
