The maker publishes this as a project, not a product listing.

Radio equipment needs certification where you live (FCC, CE, UKCA, ISED, Anatel). Some devices are uncertified or restricted in Brazil. Buyers are responsible for their local law.

Bring along: An ESP32-C3 board, the OLED-encoder module, buzzer, motor, LiPo and a 3D printer.
Keep in mind: Wired by hand; no radio features are used by the firmware yet.

What’s published

Schematics published

README embeds a rendered schematic diagram (image, not source) plus a full wiring list, and links a Thingiverse case; despite a CERN-OHL-S 'hardware' license badge, no KiCad/Gerber/BOM source file is actually in the repo.

Research notes

Repo tree (gh api) has only Firmware/*.ino, LICENSE, and LICENSE-HARDWARE (CERN-OHL-S v2 text) - no .kicad_sch/.kicad_pcb/gerber/bom files exist despite the 'Open Hardware' badge and CERN-OHL-S file; the only schematic artifact is a rendered PNG image linked from the README, and the enclosure is a separately-licensed third-party Thingiverse upload, not part of the repo.

Source & revision notes

Maker listing checked Sep 17, 2026. Detailed documentation reviewed Sep 17, 2026. Not hands-on tested.

Parts list, wiring and features were read from the README at commit ee8b620 (May 2026). Firmware release 1.1.1 is dated 2025-12-29.

Nothing is sold: this is a parts list plus firmware and a Thingiverse enclosure. Availability is shown as unconfirmed because there is no product to buy.

The maker suggests a custom PCB and BLE/Wi-Fi integrations as future ideas; the shipped firmware runs offline.

Capability corrected 2026-09-19: this entry carried a 5 GHz Wi-Fi flag that its own recorded specifications do not support. Removed rather than guessed; if the maker documents 5 GHz, add it back with the source.

Reviewed at commit ee8b6204977a9ba5fd6105870cb0c6dedb18a522. The photo is the maker’s screenshot of the built device.
