Metamer sao
About the Metamer sao PCB
Metamer sao is an open source PCB design by eosti, published on GitHub under the MIT license. It is a 2-layer board measuring 51.9 × 57.8 mm, with 43 components from 29 distinct parts.
Other key parts include the LP5018RSMR, C38663 and PY32F002BF15U. By type, the board carries 18 diodes, 12 resistors, 6 capacitors, 4 ICs, 2 connectors and 1 test point.
From the project
v2 of the badge (first seen at Hackaday 2024) can be found in the v2altium directory, though it's just boardfiles and schematic PDFs. Because reasons I had to port it into KiCAD for v2.1, which can be found in the v2.1kicad directory along with all generated gerbers and PnP files
v2 of the badge (first seen at Hackaday 2024) can be found in the v2altium directory, though it's just boardfiles and schematic PDFs. Because reasons I had to port it into KiCAD for v2.1, which can be found in the v2.1kicad directory along with all generated gerbers and PnP files required for assembly. The generators directory has some code for auto-generating C data structures for normalizing brightness.
