What is PCB Cupid Shop?

PCB Cupid Shop is the official e-commerce site of PCB Cupid, a hardware company based in Bengaluru, India.

• URL: shop.pcbcupid.com
• What: self-designed, locally manufactured open-source hardware modules
• Key trait: all modules under the CERN-OHL-P open-source-hardware license

As the official site puts it, the Shop stocks "the components engineers actually reach for" — from dev boards to connectors, sensors, and power modules.

The parent company: PCB Cupid

To understand the Shop, you need the full picture. PCB Cupid is built on a belief: the gap between a napkin idea and a manufactured board should be measured in days, not months.

Three pillars

Circuit Spell: AI-driven PCB design

The flagship tech is Circuit Spell — describe your hardware in plain English and get a production-ready PCB schematic in minutes, with routing, placement, and export to KiCad/Altium/Eagle. Average design time is 4.2 minutes (vs weeks with traditional tools).

PCB Cupid's origin is notable: it started by publishing open-source module designs, and Circuit Spell grew from that foundation. The Shop is PCB Cupid's origin.

Why it matters

1. Open source, for real

Every module is under CERN-OHL-P (CERN Open Hardware Licence v2 - Permissive). It permits:

• Use, modify, and adapt for any purpose
• Manufacture and sell products based on the designs
• Distribute and share the designs and documentation
• Create derivative works

You're not just allowed to use it — you're allowed to modify and sell it.

2. Full source with every module

Every module ships with KiCad source, Gerbers, BOM, and firmware — download, fork, or order directly.

3. A trusted starting point

As the founder puts it, "makers wanted to build faster, and they were hungry for a starting point they could actually trust." Verified, documented boards let engineers build on proven designs instead of starting from scratch.

Caveats

• India-based, rupee pricing: international shipping, customs, and currency conversion apply for buyers outside India
• Prices fluctuate: with exchange rates and sales
• Safety/regulatory responsibility is yours: CERN-OHL-P makes no warranty of fitness for a particular application — validate designs before use in safety-critical products
• Circuit Spell designs are your responsibility: you own your designs, but you also own the verification
