LPC810 Breakout Board

This basic Arm Cortex-M0+ NXP LPC810 breakout board features a FTDI programming header, USB (mini-B) connector for power only, a LM117-3.3v voltage regulator, power LED, ISP and Reset buttons and a standard 2×5-pin 0.05″ SWD debug connector. All pins are brought out to the edge of the board. Three PCBs from OSHPark.com cost me $6.55 […]



PCB Design Tutorial [Altium]

This tutorial covers schematic entry and PCB design. Most of this material could be applied to any design tool; however, this tutorial focuses on Altium Designer/DXP/Protel.The first part of the tutorial consists of a set of slides which contain instructions for PCB design, and an overview of each step in the PCB design process.

The second part of this tutorial consists of a series of videos which go through each part of the PCB design process step-by-step using Altium Designer/DXP/Protel (Altium Designer 6.9 was used). Watching all videos will take you through a PCB design from start to finish; however, the videos are divided into the separate design steps so that you don’t need to watch all of them to learn a specific skill.

Tutorial Videos
Drawing Schematics
Creating a new PCB project, creating a new schematic sheet, and drawing schematics for PCB design.(This is a 3 part video)

Routing Diferential traces in Cadsoft Eagle

Eagle supports basic differential routing. To make a pair of traces a differential  pair, both signals should have the same name with _N and _P at the end. For example `MIC_N` and `MIC_P`. When you try to route this signal it will be seen as a differential  pair and will be routed as one. This means that both the traces will be routed at the same time as shown in the image above. Wen one of the two traces is selected both will be routed at the same time. To route only one trace, click on the trace to route it and when both traces are selected press escape to only route the one you selected.
