Open the updated schematic
The High Boy V2_03 record contains the user-supplied original PDF, dated September 29, 2026. It covers power, ESP32-P4/C5 processors, radio, RFID/NFC, display and audio peripherals, GPIO/microSD connectors, and USB/UART. Search Highboy or High Boy V2_03 in the guide. Use PDF page 7 for the GPIO/microSD connector sheet and page 8 for USB/UART.
Match the hardware revision
V2_03 comes from the supplied filename; the drawing revision boxes are blank. Original sheet totals are inconsistent, and prototype annotations remain present. Final production status and electrical correctness have not been independently verified. The historical REV 2.2 MVP uses ESP32-S3 and has a separate connector-label image. Do not transfer pin assignments between the two revisions.
Coverage and rights
This is a circuit schematic, not a complete physical connector-location map. All eight pages were visually reviewed, and the original PDF bytes are preserved. Manufacturer artwork retains its own rights; guide inclusion does not establish permission for commercial printing or reuse. This content update is collection snapshot 2026.10.1 within First Edition / 2026. Previously published desktop installers retain their bundled catalogs; the updated schematic is available here in the browser guide.
