Speakeasy panel 3x3: common questions

What microcontroller does the Speakeasy panel 3x3 use?

The Speakeasy panel 3x3 is built around the ESP32-S3-MINI-1U-N4R2, from the ESP32 family.

How big is the Speakeasy panel 3x3 PCB?

The Speakeasy panel 3x3 measures 127 × 149 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Speakeasy panel 3x3?

17 components, from 15 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 Speakeasy panel 3x3 design files?

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

Can I use the Speakeasy panel 3x3 design in my own project?

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

Can I test firmware for the Speakeasy panel 3x3 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.
