/claim #47
/claim #44

Archived bounty issues:

• Create ESP32 module circuit example similar to hardware academy (schematic only) docs-old#47
• ESP32 PCB Layout and Routing docs-old#44

Summary

• add a schematic-only ESP32-WROOM style tutorial
• include a live schematic preview with 3.3 V regulation, EN reset, IO0 boot, USB-UART wiring, decoupling, and I2C/SPI breakout headers
• add a PCB layout/routing section with a PCB-focused preview, module-edge placement, USB/regulator/header placement, and routing guidance tied to Espressif layout recommendations
• document the main ESP32 pin groups and PCB adaptation checklist

Verification

• npm exec --yes prettier -- --check docs/tutorials/esp32-module-schematic.mdx
• bun run format:check
• bun run typecheck
• bun run docusaurus build
• git diff --check

Note: npx tscircuit docs/tutorials/esp32-module-schematic.mdx snippet compile currently fails before reading this document because the installed tscircuit@0.0.1774 dependency graph errors with Export named ms not found in module .../circuit-json/dist/index.mjs.
