A short, curated guide — not an automatic related dump. Figures come from SubMouse's safe-for-work directory when we have them.
r/electronics (about 1.4M members, directory rank #740) covers component-level electronic circuits. Single-board computer projects, PC hardware shopping, general DIY and 3D-printed parts each fit better when the thread is not circuit design.
Stay on electronics for schematics, components and circuit discussion. Use raspberry_pi for Pi projects, hardware for PC parts, DIY for general builds, and 3Dprinting for printed parts.
r/electronics — Electronic circuits at the component-level
Discussion and news about component-level electronic circuits.
Raspberry Pi - More than just magic mirrors and kodi!
When to choose it: Raspberry Pi projects and SBC builds.
Why it is here: Public description: Raspberry Pi beyond magic mirrors and Kodi (about 3.3M members, rank #317).
How it differs from r/electronics: Pi/SBC projects versus component-level electronics.
/r/hardware: a technology subreddit for computer hardware news, reviews and discussion.
When to choose it: PC and consumer hardware rather than circuits.
Why it is here: Hardware discussion community in the tech neighbourhood.
How it differs from r/electronics: Finished hardware products versus circuit design.
DIY
When to choose it: General do-it-yourself projects.
Why it is here: See diy vs homeimprovement on SubMouse.
How it differs from r/electronics: Broad DIY versus electronics specialty.
Welcome to R/3D Printing! Come for the Benchy, stay for the Calibration!
When to choose it: 3D-printed parts and printers.
Why it is here: Directory related neighbourhood for electronics makers.
How it differs from r/electronics: Additive manufacturing versus circuit electronics.
