About the Motor Speed Controller PCB

Motor Speed Controller is an open source PCB design by SelvaUx, published on GitHub. It is a 2-layer board measuring 132.5 × 135 mm, with 12 components from 10 distinct parts.

Other key parts include the ICM7555xP and L293. By type, the board carries 4 resistors, 2 ICs, 2 diodes, 1 module, 1 connector and 1 switch.

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.
