Caden final: common questions
What microcontroller does the Caden final use?
The Caden final is built around the esp32_dev, from the ESP32 family.
How big is the Caden final PCB?
The Caden final measures 99.1 × 69.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Caden final?
61 components, from 34 distinct parts. The full bill of materials is listed on this page.
Where can I download the Caden final design files?
From the c3n3/desg-of-senio repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Caden final design in my own project?
The repository has no license, so all rights stay with c3n3. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Caden final 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.
