PCB Routing Pt3
Finally Finished Routing the project!!!!!!
Took a while but I ended up using layer 3 as a mixed power and signal plane insteed of a solid power plane. I am happy with how it turned out. I still might add TX and RX lines to the UPDI header, so you can do serial print.
Overall very happy. Now I have to finish the silkscreen labels, do the documentation :/ , and test it (yay).
PCB Routing
MicroDev128-32
Started routing everything for the whole board. I am sick of routing a good seeming line and then ripping it up 20 times.
________________________________________________________________Project Overview
Based on the AVR128DB32, with the LT8653S switching power regulator. It has:
- Up to 2 amps on both the 3.3v and 5v lines.
- 128kB Flash and 16kB SRAM
- MVIO on 4-pins with 3.3v, 5v and EXTERNAL source presets
- UPDI Programing
- Arduino Nano sized footprint
- Aims to have a better price to performance ratio than
Arduino (not hard considering a Genuine Uno is $40 NZD (About 20 USD)
More to come as I hopfully soon finish this project!
PCB PT2
This time:
I have changed the voltage regulator to be the LT8653S (smaller footprint)
I have relaid the board (again)
I have started routing some basic data lines and the crystal.
I have updated all footprints
More to go!

Ignore what it says I spent 1.5 hours on this (it logged in another project).
has basic API fetching now!
