About the P8x peripheral card PCB

P8x peripheral card is an open source PCB design by ksr, published on GitHub. It is a 4-layer board measuring 280 × 140 mm, with 101 components from 43 distinct parts.

Other key parts include the 74HCT30, 74HCT138, 74HCT32, 74HCT08 and 74HCT161. By type, the board carries 37 capacitors, 33 ICs, 5 resistors, 4 LEDs, 3 connectors and 2 crystals.

From the project

Generated by generators/genkicad.py from the canonical geneagle netlist (CARDS["peripheral-card"]), same standard as the memory card: 4-layer (F/B signals, In1=GND, In2=VCC planes), a bypass cap above each IC, a labelled LED/jumper bank, part values on silk. Routed with Freerouti

P8x peripheral card: common questions

How big is the P8x peripheral card PCB?

The P8x peripheral card measures 280 × 140 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the P8x peripheral card?

101 components, from 43 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the P8x peripheral card design files?

From the ksr/p8x repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the P8x peripheral card design in my own project?

The repository has no license, so all rights stay with ksr. Use it as a reference, and ask the author before reusing the design.
