From the project
Hardware design monorepo with software-grade CI/CD. KiCad PCB projects with automated ERC/DRC, multi-fab rule validation, schematic & BOM checks, and auto-generated board documentation.
Fully routed 64 × 56 mm, four-layer engineering prototype, revised 2026-09-04. The compact layout is 35.42% smaller than the previous 74 × 75 mm board. The four buttons retain 15 mm spacing and the component-side order VOL− / MODE / VOL+ / BATTERY.
Battery J1 feeds an AO3401A reverse-polarity stage and two TPS63070 buck-boost regulators: 3.307 V for the ESP32-S3/RTC and 4.985 V for the MAX98357A amplifier. GPIO18 enables the audio rail. USB-C is data-only. The RTC, switched OLED bus, wake buttons and common-anode RGB indicator remain.
