Research notes

IMPORTANT for rebuilders: the Highboy_PCB repo README states these files are Rev 2.2, a validated MVP prototype built around a single ESP32-S3 — NOT the final production design. The maker's own site (highboy.com.br, checked 2026-09-27) describes a different, not-yet-published dual-MCU final architecture (ESP32-P4 app processor + ESP32-C5 comms processor); those final schematics were not found published anywhere. Firmware (TentacleOS) is also open on GitHub but omitted here per instructions to exclude firmware.

What still needs checking

Battery figures conflict within the maker page.
Final dimensions, weight, firmware release state, schematic availability and accessory-by-accessory compatibility need confirmation.
