ESP32 build guides and board references
Answers for getting an ESP32 project off the breadboard and into a finished device: cases, power, displays, wiring, ordering PCBs, and reference pages for the boards we see most.
- Guides
- ESP32 breadboard to finished device: Perfboard or your own PCB, a case, USB-C power, and when to hand it off.
- ESP32 case: Models for your board, PLA or PETG, measuring, USB and button access.
- ESP32 power over USB-C: CC resistors, regulator limits, Wi-Fi peaks and the brownout message.
- ESP32 display not working: White screen, wrong colours and dead touch, with the CYD as the main example.
- ESP32 pins to avoid: What to check in AI-generated wiring before you solder.
- Have your AI agent design an ESP32 device: Connect Claude Code or Codex to the Protoship MCP server.
- Comparisons
- JLCPCB vs PCBWay vs AISLER vs CircuitHub: Five bare and two assembled boards to Germany: price, time, customs.
- Order a PCB yourself or have your build finished: Steps, fees and time for each route, and when doing it yourself is better.
- Boards
