CNC ESP32: common questions
What microcontroller does the CNC ESP32 use?
The CNC ESP32 is built around the ESP32-DevKitC, from the ESP32 family.
How big is the CNC ESP32 PCB?
The CNC ESP32 measures 63.8 × 95.8 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the CNC ESP32?
19 components, from 9 distinct parts. The full bill of materials is listed on this page.
Where can I download the CNC ESP32 design files?
From the IagoAbreu-Core/CNC_ESP32 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the CNC ESP32 design in my own project?
The repository has no license, so all rights stay with IagoAbreu-Core. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the CNC ESP32 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.
