Electronics Design

Assignment Objective

Design and simulate a custom PCB that includes a microcontroller, power circuitry, and at least one input and output device, preparing it for future weeks of embedded programming.

Process & Documentation

Step 1 · Schematic Capture

Drew the schematic of my board, including the microcontroller, programming header, power supply, LED, and button. Double-checked pin connections against the datasheet.

Step 2 · Footprints & Libraries

Selected or created footprints for each component, making sure pad sizes and spacing match the components available in the lab inventory.

Step 3 · PCB Layout

Routed the traces, added ground planes, and respected design rules for trace width and clearance. Organized components to keep the board compact and easy to solder.

Step 4 · Checks & Exports

Ran electrical rule checks (ERC/DRC), fixed warnings, and exported the milling/production files that will be used in the Electronics Production week.
