From the project

Compact Open Multi-sensor Platform & Apparat.

Compact Open Multisensor Platform & Apparatus

/ˈkompitɕ/ — Croatian for "little computer" (and the word you'd only use for an actual friend, not a stranger).

A fully open-source, offline-first, ML-capable wrist-mounted sensor platform. The hardware collects. The firmware infers. You own everything.

Page: https://porupski.github.io/kompic-wearable/

Kompic̄ is a wrist-mounted sensor platform built around an ESP32-S3 (dual-core, 8 MB PSRAM, 16 MB flash) with a sensor suite denser than any open-source watch, and enough on-device compute to run real neural networks on that data — sleep…

Kompic Mk1b: common questions

What microcontroller does the Kompic Mk1b use?

The Kompic Mk1b is built around the ESP32-S3-WROOM-1U-N16R8, from the ESP32 family.

How big is the Kompic Mk1b PCB?

The Kompic Mk1b measures 44.5 × 50.6 mm, has 4 copper layers and is 1 mm thick.

How many components are on the Kompic Mk1b?

121 components, from 55 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Kompic Mk1b design files?

From the porupski/kompic-wearable repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Kompic Mk1b design in my own project?

Yes, under the terms of its GPL-3.0 license, which porupski chose for the repository.

Can I test firmware for the Kompic Mk1b without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
