About the Pi debug swd adapter PCB
Pi debug swd adapter is an open source PCB design by mikeysklar, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 26.6 × 11 mm, with 2 components from 2 distinct parts.
From the project
Passive adapter: Raspberry Pi Debug Probe (JST-SH 3-pin) to standard 2x5 1.27mm ARM Cortex SWD header. Single-sided, home-etched.
Connects the $12 Raspberry Pi Debug Probe to a standard 2x5 SWD connector.
Voice dictated to Claude, which sourced the parts and wrote out the KiCad schematic and PCB board file. No MCP server, no skill, no reference design.
See CLAUDE.md for what it was used. This file represents the on-going changes I had Claude make after the first pass.
Fabrication: a Bantam CNC to cut the single sided PCB blanks, and an xTool F1 Ultra fiber laser to etch, silkscreen, and expose the pads under a green resin layer was applied. The steel business card stencil was cut on the same laser.
