NoU3-Panelized: common questions
What microcontroller does the NoU3-Panelized use?
The NoU3-Panelized is built around the ESP32-S3FN8, from the ESP32 family.
How big is the NoU3-Panelized PCB?
The NoU3-Panelized measures 138 × 168 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the NoU3-Panelized?
113 components, from 60 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the NoU3-Panelized design files?
From the AlfredoSystems/NoU3-Hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the NoU3-Panelized design in my own project?
The repository has no license, so all rights stay with AlfredoSystems. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the NoU3-Panelized without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
