Autofeedermod: common questions

What microcontroller does the Autofeedermod use?

The Autofeedermod is built around the ESP32-C6-Zero, from the ESP32 family.

How big is the Autofeedermod PCB?

The Autofeedermod measures 56 × 54 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Autofeedermod?

39 components, from 28 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 Autofeedermod design files?

From the wabolabs/autofeedermod repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Autofeedermod design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which wabolabs chose for the repository.

Can I test firmware for the Autofeedermod 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.
