Keyboardv1: common questions
What microcontroller does the Keyboardv1 use?
The Keyboardv1 is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the Keyboardv1 PCB?
The Keyboardv1 measures 304 × 146 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Keyboardv1?
217 components, from 27 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 Keyboardv1 design files?
From the matia6170/keyboardv1-KiCAD repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Keyboardv1 design in my own project?
The repository has no license, so all rights stay with matia6170. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Keyboardv1 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.
