Sonatino: common questions

What microcontroller does the Sonatino use?

The Sonatino is built around the ESP32-S3-WROOM-1U, from the ESP32 family.

How big is the Sonatino PCB?

The Sonatino measures 65 × 30 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Sonatino?

117 components, from 58 distinct parts. The full bill of materials is listed on this page.

Where can I download the Sonatino design files?

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

Can I use the Sonatino design in my own project?

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

Can I test firmware for the Sonatino 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.
