About the Chufe PCB
Chufe is an open source PCB design by piruetasxyz, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 50 × 65 mm, with 19 components from 13 distinct parts.
Other key parts include the URA2412YMD-20WR3 and L7805. By type, the board carries 5 diodes, 5 resistors, 3 connectors, 3 capacitors, 2 ICs and 1 transistor.
From the project
popusintes - chufe
chufe is an open source hardware Eurorack power supply by piruetas. It takes 12 V DC from a barrel jack, with reverse polarity protection, and outputs ±12V (from a 20 W isolated DC-DC converter) and +5V (from an L7805 linear regulator) on a 16-pin Eurorack power header and a 4-pin Molex KK-396 connector, with an LED for each rail. It is designed to feed a power bus such as chufebu. The design is made in KiCad 10 with KiCad's standard libraries plus one third-party part, included in terceros/. Hardware is licensed under CERN-OHL-P-2.0 and documentation under CC-BY-SA-4.0 (see LICENSE.md).…
