METRONOME
About the METRONOME PCB
METRONOME is an open source PCB design by SelvaUx, published on GitHub. It is a 2-layer board measuring 55.5 × 74.5 mm, with 9 components from 6 distinct parts.
By type, the board carries 3 capacitors, 3 resistors, 1 IC, 1 battery holder and 1 speaker.
From the project
A collection of 10 production-ready schematic & PCB layout designs From fundamental analog circuits to motor control systems — all designed in KiCad
I build for the messy, low-bandwidth, real world — where people need technology that actually functions. My engineering philosophy is simple: offline first, privacy always, real hardware required. I don't trust solutions that work only in ideal conditions.
From custom AI assistants to fiber fault detection engines, from IoT aquaculture platforms to portfolio sites with mini-labs inside — the list doesn't stop because the curiosity doesn't stop.

METRONOME: common questions
How big is the METRONOME PCB?
The METRONOME measures 55.5 × 74.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the METRONOME?
9 components, from 6 distinct parts. The full bill of materials is listed on this page.
Where can I download the METRONOME design files?
From the SelvaUx/PCB-Design-Internship-Circuit-Portfolio repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the METRONOME design in my own project?
The repository has no license, so all rights stay with SelvaUx. Use it as a reference, and ask the author before reusing the design.
