Hyperscale
About the Hyperscale PCB
Hyperscale is an open source PCB design by jmgrosen, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 103 × 26.3 mm, with 17 components from 12 distinct parts.
By type, the board carries 7 capacitors, 4 resistors, 2 ICs, 2 switches, 1 connector and 1 buzzer.
From the project
A kitchen scale that helps you follow a recipe.
A kitchen scale that helps you follow a recipe.
Export Gerbers from KiCAD for the PCB. Build STLs from OpenSCAD for the case.
For the firmware, install the Xtensa rustc target and espflash as described in the Rust on ESP Book. Then cargo espflash flash.
The physical design files are licensed under the CERN Open Hardware Licence Version 2 - Permissive.
The firmware code is licensed under MIT. However, due to its use of Slint, the resulting firmware as a whole is licensed under GPLv3.
