Clocking FPGA and LAN8720 with PIC32MZ

This is my fifteen week in AESTE finishing up my PCB design project. ..-“””””-.. .’ ___ ‘. / .”\ `\ \ ; /, ( | ; ; /_…

PCB design is NOT easy!

This is my fourteen week in AESTE with Schematic done proceeding to PCB design about 50% done. The PCB design is a Four-layer board, signal -ground – power…

PIC32MZ PPS feature

This is my thirteen week in AESTE. Getting closer and closer to the end of my internship~  This week I continue with drawing Schematic. 😴 💤 💩 😈…

Board Modifications and Technical Layers

While entering the last stages of creating the PCB, there are still some changes to be made to the circuit. In addition to these modifications, this week the…

Routing the Board

This week’s post is relatively short, as I spent most of the time doing the actual routing, so nothing much to talk about here! However, I will highlight…

Placing Components and Decoupling Capacitors

Last week after finishing the schematics I started with assigning and creating the components footprints. This was the first thing I finished this week, though it took some…

Schematics Modifications

Now for real, the circuit is finished, and I have started with assigning and creating the footprints for the components. There are no one major updates this week,…

Powering the Board and Connecting Ports

I continues working on the schematics this week. By now, almost all the major components in the circuit are connected. Last week I connected the Ethernet jack, SD…

Oscillator Sharing between ICs

In our PCB, we have an FPGA, and PIC18 microcontroller. It is our intention to share one oscillator between the two ICs, hence reducing the cost, and sparing…

Ethernet and SD-Card Connections

In the first two weeks of the project I was reading and trying to grasp the basics of PCB design and KiCAD. This week I put this knowledge…

Starting with Eeschema

Resuming from last week, I continued working on the PCB design for our product. Last week I talked about my experience with learning the basics of designing PCB…

PCB Designer Life

Have you ever been thrown into the middle of ocean, and you don’t even know how to swim? Well, I have lived this experience, both literally and figuratively….

PCB Complete, Documentation Done and Final Thoughts

In my final week, we wrap up with the PCB design of the product prototype and retrace & document the work completed in my nine weeks at Aeste….

PCB Design and the FreeRouting Autorouter

Work on designing the PCB layout continues in earnest. We encounter a few software issues relating to the hardware of the task, which prompt some worried thoughts. As…

Week7: PCB Component Placement and Decoupling Capacitors

With the footprints done, wrestling with PCB design continues as usual with component placement and routing. Also this week, I hit a minor snag with regards to simple…
