J.A.R.V.I.S ESP32 Diagnostic Cyberdeck

by HeroicCodey · Intermediate · manifest draft — being verified

A compact ESP32 diagnostic terminal with a color display, four-button interface and protected 18650 power source, documented with firmware, PCB and enclosure files.

HeroicCodey developed J.A.R.V.I.S as a small field-oriented electronics console whose monochrome-inspired carousel UI runs on an ESP32. The repository records the component-selection process and publishes Arduino firmware, a KiCad board, a STEP enclosure model and an exact linked Markdown BOM.

Notes

Official README, Markdown/CSV BOMs, journal, firmware, KiCad board, repository metadata and STEP file rechecked at commit e274c1abe225dc9973593d4c47a4ae482aed1066 on 2026-11-02. Kept as draft because the exact BOM display uses an ILI9163C controller while the README specifies ST7735; the README also adds an A7670C cellular module and TP4056/BMS that the BOM omits, while the journal calls V0.01 the basic version without SIM integration. BOM.csv omits the battery, the journal discusses a different 38-pin ESP32 variant, no license is declared, and the repository does not document a completed hardware test.
