Base board
About the Base board
Base board is an open source PCB design by GeniePod, published on GitHub under the CERN-OHL-S-2.0 license. It is a 6-layer board measuring 90 × 90 mm, with 216 components from 78 distinct parts.
Other key parts include the ESDA25W, STUSB4500QTR, TPS7A0518PDBZ, TPS51396ARJER and TPS22992RXPR. By type, the board carries 107 capacitors, 54 resistors, 22 ICs, 11 connectors, 9 inductors and 4 diodes.
From the project
GeniePod Home V1 hardware: MVP testing build, wiring, BOM, and planned interface-board/enclosure docs.
GeniePod Home V1 board layouts, derived from the schematics in ../schematic/.
empty — nothing here yet. The schematics arrive first; the layout follows once the Home V1 interface-board schematic stabilizes.
- Tool: KiCad 8.x. Gerbers + drill + position file committed alongside .kicadpcb so the board is manufacturable without a KiCad install. PNG renders make GitHub previews useful. - Layer stack: 4-layer for any board carrying I2S clocks at 24-48 kHz with ESD protection on USB. 2-layer is fine for the simplest passthrough. - DFM target: JLCPCB defaults unless a board specifically needs…
