About the Drumkid PCB
Drumkid is an open source PCB design by mattybrad, published on GitHub under the MIT license. It is a 2-layer board measuring 90 × 140 mm, with 57 components from 32 distinct parts.
Other key parts include the 6N138. By type, the board carries 15 connectors, 15 resistors, 9 diodes, 8 switches, 4 capacitors and 1 IC.
From the project
DrumKid is designed using KiCad. You can edit the KiCad files to produce a custom DrumKid PCB, or just use the Gerber files provided to order a DrumKid PCB from a manufacturer. The latest working, tested PCB is V6. V7 is coming soon with (very) minor revisions, and V8 might invol
DrumKid is designed using KiCad. You can edit the KiCad files to produce a custom DrumKid PCB, or just use the Gerber files provided to order a DrumKid PCB from a manufacturer. The latest working, tested PCB is V6. V7 is coming soon with (very) minor revisions, and V8 might involve some surface-mount components because I've just learnt how to design/order pre-assembled boards.
