Posting a sneak peek of the integrated control board for Tiny Engineer! It includes an integrated servo controller, audio amplifier, and USB port. You simply plug the ESP32 into the gold pin headers, servos, speaker and you’re ready to go. I’m still finalising the design before ordering the first batch of test boards. More updates soon!

Quick status update: the latest revision has been sent for manufacturing and the boards are currently in production. 🎉 Once they arrive, I will assemble one and do a full hardware bring-up before merging this PR. Fingers crossed I didn’t invent any new creative PCB mistakes this time 😅 |

Build a production-ready integrated PCB that consolidates the Tiny Engineer electronics currently implemented as separate modules and connections.
The board should integrate the core supporting circuitry, including:
The ESP32 integration is intentionally left open at this stage. The design should evaluate whether the ESP32 should be assembled directly onto the PCB or remain a pluggable/module-based component.
The final design should be ready for PCB fabrication and assembly by a single supplier, including schematic, PCB layout, BOM, component placement data and manufacturability checks. JLCPCB is the current target manufacturer/assembler, so component selection and design decisions should favor parts available through their assembly service where practical.
The goal is to replace the current collection of modules and wiring with a compact, reproducible and assembly-ready board suitable for future Tiny Engineer builds.
