YAMMU ControlBoard v05
Zergie/YAMMU
A Multi Material Unit (MMU) for eight filaments that can also function as a filament dryer and can keep it dry while printing. The design is heavily inspired by voron and their printers.

Power supply test for Cockcroft Walton converter
Cwpsu is an open-source printed circuit board by CosmicPi, from the CosmicPi/psutest repository on GitHub. It is a 2-layer board of 100 × 25 mm with 49 parts on 30 nets, routed with 185 tracks and 51 vias.
It is built around the BAT54SW and BSS123. Its parts include 21 capacitors, 11 diodes, 6 connectors, 4 resistors and 1 transistor.
Power supply test for Cockcroft Walton converter
Hardware tested and working as expected with a Digital Multi-Meter, need to check it with a scope. It is designed to work with the Ketek PM3325 SiPM module. In the meantime check out the LTSpice model!

The 45 most common of 49 parts.
It measures 100 × 25 mm and has 2 copper layers, 1.6 mm thick.
49 parts, built around the BAT54SW and BSS123. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the CosmicPi/psutest repository on GitHub, at the commit this page was made from: the board is cwpsu.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask CosmicPi before reusing the design.
