EnokiEEG-v2-rounded: common questions

What microcontroller does the EnokiEEG-v2-rounded use?

The EnokiEEG-v2-rounded is built around the ESP32-S3-PICO-1-N8R2, from the RP2040/RP2350 family.

How big is the EnokiEEG-v2-rounded PCB?

The EnokiEEG-v2-rounded measures 39.5 × 39.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the EnokiEEG-v2-rounded?

92 components, from 33 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 EnokiEEG-v2-rounded design files?

From the io-tronic/EnokiEEG repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the EnokiEEG-v2-rounded design in my own project?

The repository has no license, so all rights stay with io-tronic. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the EnokiEEG-v2-rounded without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
