About the Xyab PCB
Xyab is an open source PCB design by plinkysynth, published on GitHub under the MIT license. It is a 2-layer board measuring 43.2 × 128.3 mm, with 68 components from 25 distinct parts.
Other key parts include the LM4040DBZ-2.5, SN74LVC1G17DBV, HCPL-0631, DAC7554IDGS and TL072. By type, the board carries 29 resistors, 12 capacitors, 11 connectors, 8 ICs and 8 diodes.
From the project
a public release of the plinky sw and hw
Stijn from This Is Not Rocket Science routed the original Version 3. Steve / Okyreon from denki oto added the LPZW midi circuit to allow plinky to have on-board midi without the expander. Kay** from LPZW Modules then contributed a circuit to fix the input noise, and then polished everything into a 'Version 3.1', which is the current version linked here. Kay also was one of the original people who helped me with the hardware design of V1 and V2.
