ESP32N1: common questions
What microcontroller does the ESP32N1 use?
The ESP32N1 is built around the ESP32, from the ESP32 family.
How big is the ESP32N1 PCB?
The ESP32N1 measures 78 × 26 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the ESP32N1?
53 components, from 32 distinct parts. The full bill of materials is listed on this page.
Where can I download the ESP32N1 design files?
From the whitecatboard/whitecat-hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the ESP32N1 design in my own project?
The repository has no license, so all rights stay with whitecatboard. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ESP32N1 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.
