About the Einstein-Boltzmann Main Board
Einstein-Boltzmann Main Board is an open source PCB design by CarlosCraveiro, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 161.8 × 100 mm, with 57 components from 28 distinct parts.
Other key parts include the ADA4898-2 and AD633ANZ. By type, the board carries 20 resistors, 16 capacitors, 9 connectors, 6 diodes, 3 ICs and 3 switches.
From the project
Remake of the board of the 5-th EPO (2017), using KiCAD 7.0, to measure the Boltzmann constant through the analysis of the thermal noise of a resistor.
So the schematic ideia is not mine, I just adapt and documented it so I could manufacture the board.
The DRC Custom Rules used on this project came from a gist made by darkxst, Gist name: rules.txt.
- KiCAD version 7.0 - KiCAD Addon kicad-action-scripts (via stitching)
If you use nix, to have access to KiCAD 7.0, on the project's directory type:
Observation: I intend to continue working on the project, I just need time.
