PCB Design Tutorial

Introduction

This tutorial will go over how to get started with your PCB design, as well as go over the things you will use while designing your PCB.

PCB Text

Introduction

Text is important on PCB layouts to identify the designers, project, version, components, etc. Typically, text can be placed on a silkscreen layer that sits on top of the copper. However, our manufacturing process in PRLTA 109 only supports text that is milled on the TOP COPPER or BOTTOM COPPER layers.

**Note: **It is required that all PCB designs have your name, course, and team number so that the Peralta Engineering Studios staff can distinguish your board from others.

Peralta 103 Resources

What equipment is available at each of the benches?

Function Generator (5 MHz)

PIC Curiosity Nano and the TC74 I2C Temp Sensor

Objectives

The goal of this tutorial is to introduce you to the timer subsystem, implement a timer using an interrupt-based design, and use that timing to perform some I$^{\text{2}}$C communication with the TC74 Temperature Sensor.

Placing and moving components in Cadence PCB Editor

While it is easy to place components using the mouse, most designs require precise placement of some components (e.g., to align parallel headers). This tutorial walks through how to place components at a specific X-Y coordinate, determine the X-Y coordinates of a component, measure the distance between two components, move an existing component to a specific X-Y coordinate, and move an existing component relative to its current location.

Power Supplies 101

What are the components of a basic power supply subsystem?

  1. Source of power - battery, AC adapter, solar
  2. Input electronic noise filtering circuit
  3. Voltage regulator to provide a constant supply voltage
  4. Output electronic noise filtering circuit

What are the design considerations for a battery-operated circuit?

How many Amp-Hours of capacity are needed?

Printing Non-String Variables to the PSoC UART

Q: How do I print an integer (or other non-string variable) to the PSoC UART?

PSoC 4 Hardware Development Kits

There are several Cypress Programmable System on a Chip (PSoC®) hardware development kits available for use in designs. The list below describes strengths of each kit and provides links to documentation.
