Extraice: common questions

What microcontroller does the Extraice use?

The Extraice is built around the ESP32-S3-FN8, from the ESP32 family.

How big is the Extraice PCB?

The Extraice measures 40 × 57 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Extraice?

72 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Extraice design files?

From the elkel53930/extraice4 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Extraice design in my own project?

Yes, under the terms of its MIT license, which elkel53930 chose for the repository.

Can I test firmware for the Extraice 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.
