The controller board is designed in atopile and manufactured via JLCPCB.
Features
- ESP32-S3 microcontroller with WiFi/BLE
- On-board AC-DC converter (100-240V AC → 5V DC) - direct mains power
- USB Type-C for programming/debugging (also provides backup power)
- MAX31855 K-type thermocouple interface for precise temperature measurement
- External SSR control for heater switching (supports 25A panel-mount SSRs)
- Pressure sensor input with 5V→3.3V level shifting
- Status LEDs for system state indication
See pid-controller/README.md for detailed board documentation.

Questions
How big is the Layouts PCB?
It measures 210 × 60 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Layouts use?
32 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Layouts KiCad files?
From the SuperCoolAlan/esp32-espresso repository on GitHub, at the commit this page was made from: the board is pid-controller/layouts/default/default.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Layouts design in my own project?
Its repository states no licence, so its author keeps all rights: ask SuperCoolAlan before reusing the design.
