About the Relelauta PCB
Relelauta is an open source PCB design by chiplet, published on GitHub. It is a 2-layer board measuring 100 × 100 mm, with 150 components from 20 distinct parts.
Other key parts include the TLV75533PDBV. By type, the board carries 45 diodes, 35 resistors, 24 connectors, 16 transistors, 16 inductors and 12 capacitors.
From the project
Kircular Accelerator Prototype Innovative New Experience
This project uses components from digikey-kicad-library which is configured as a git submodule of this project. Git doesn't clone submodules of a project by default when the project it is cloned so this has to be done manually.

Relelauta: common questions
How big is the Relelauta PCB?
The Relelauta measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Relelauta?
150 components, from 20 distinct parts. The full bill of materials is listed on this page.
Where can I download the Relelauta design files?
From the chiplet/kapine repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Relelauta design in my own project?
The repository has no license, so all rights stay with chiplet. Use it as a reference, and ask the author before reusing the design.
