KaSe
About the KaSe PCB
KaSe is an open source ESP32 PCB design by mornepousse, published on GitHub. It is a 2-layer board measuring 296.8 × 145 mm, with 155 components from 19 distinct parts.
Its main chip is the ESP32-S3, from the ESP32 family. Other key parts include the BQ25611D, ESP32-S3-DevKitC and W25Q128JVS. By type, the board carries 64 switches, 64 diodes, 5 connectors, 4 ICs, 4 capacitors and 3 resistors.
It belongs with the keyboards designs in this gallery.
From the project
This repository contains the KiCad project and resources for the KaSe keyboard, a compact, column-staggered layout inspired by the Atreus62.

KaSe: common questions
What microcontroller does the KaSe use?
The KaSe is built around the ESP32-S3, from the ESP32 family.
How big is the KaSe PCB?
The KaSe measures 296.8 × 145 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the KaSe?
155 components, from 19 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 KaSe design files?
From the mornepousse/KaSe_PCB 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 KaSe design in my own project?
The repository has no license, so all rights stay with mornepousse. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the KaSe 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.
