Printed circuit board designs

A repository with designs of printed circuit boards (PCBs) for electronic circuits developed with KiCad. Each project has its own folder, focused on a different and specific problem.

The following projects are available:

• full-bridge DC driver Arduino Nano (carrier board)
• low-side DC driver Arduino Nano (carrier board)
• relay module 5 V optocoupler SMT 4 channels
• relay module 5 V optocoupler SMT
• power supply with linear regulator 78xx
• power supply with linear regulator lm317

Arduino Nano full-bridge DC and sensor

A PCB design to a carrier board for Arduino Nano with full-bridge circuit and voltage sensors.

Arduino Nano low-side DC driver and sensor

A PCB design to a carrier board for Arduino Nano with 2 low-side switches and voltage sensors.

Relay module 3.3/5/12 V optocoupler SMT 4 channels

A two-layer PCB design to a four-channel relay module with optocoupler.

Relay module 3.3/5/12 V optocoupler SMT

A two-layer PCB design to a single-channel relay module with optocoupler.

Premium version

This repository contains open versions which consider single-sided 1oz boards and Through-Hole Technology (THT) for components. Improved designs or boards using Surface Mount Technology (SMT) can be developed on request.

Premium versions, with additional features, extended documentation and support, are available at:
