Soily: common questions

What microcontroller does the Soily use?

The Soily is built around the ESP32-H2-MINI-1, from the ESP32 family.

How big is the Soily PCB?

The Soily measures 25 × 129.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Soily?

38 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Soily design files?

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

Can I use the Soily design in my own project?

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

Can I test firmware for the Soily 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.
