ES3ink: common questions

What microcontroller does the ES3ink use?

The ES3ink is built around the ESP32-S3-WROOM-2, from the ESP32 family.

How big is the ES3ink PCB?

The ES3ink measures 60.8 × 31 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ES3ink?

67 components, from 34 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 ES3ink design files?

From the dronecz/ES3ink 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 ES3ink design in my own project?

Yes, under the terms of its MIT license, which dronecz chose for the repository.

Can I test firmware for the ES3ink 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.
