- choosing to ignore issue that pads are too close to board edge by 0.03mm
- In future revision could add two 100n decoupling caps such as in this design. Tried to add later on but it was too tight a squeeze.
Build Instructions
S stands for socket P stands for pin
TODO
- check that two boards overlap

Questions
How big is the HagiwoBuffMult PCB?
It measures 25 × 108.3 mm and has 2 copper layers, 1.6 mm thick.
What parts does the HagiwoBuffMult use?
45 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the HagiwoBuffMult KiCad files?
From the fablabnk/HagiwoBuffMult repository on GitHub, at the commit this page was made from: the board is HagiwoBuffMult.kicad_pcb and its schematic HagiwoBuffMult.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the HagiwoBuffMult design in my own project?
Its repository states no licence, so its author keeps all rights: ask fablabnk before reusing the design.
