Raspberry Pi Zero Relay Board

I designed a custom Raspberry Pi Zero relay control board that combines a Raspberry Pi Zero development platform with multiple relay outputs for controlling external electrical loads.

The objective of the project was to allow the Raspberry Pi Zero to electronically control the relays, providing a practical interface between the low-voltage digital signals from the Pi and connected external devices.

My work involved developing the PCB layout around the Raspberry Pi Zero, organizing the relay circuitry, and carefully routing the control and power connections. Particular attention was given to component placement, signal routing, power distribution, isolation between the control circuitry and relay sections, and maintaining a clean, reliable board layout.

The project provided valuable experience in Raspberry Pi hardware integration, relay control, PCB design, digital interfaces, and hardware prototyping, while demonstrating how a compact embedded platform can be integrated with a dedicated control board for real-world automation applications.
