README.mdDellPowerTrigger
Small board that allows standard 5.5x2.1 power supply to be used for Dell Optiplex 3050 Micro.
In order for Dell 3050 Micro to recognize charger correctly, one needs to trick its power input. For that purpose, a simple circuit is needed.
Features:
- Allows 5.5x2.1mm DC input
- Has 1-wire control chip (DS2501)
- Dell-compatible 3-pin output

Questions
How big is the DellPowerTrigger PCB?
It measures 30 × 12 mm and has 2 copper layers, 1.6 mm thick.
What parts does the DellPowerTrigger use?
11 parts, built around the CUS08F30. 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.
Where can I download the DellPowerTrigger KiCad files?
From the medo64/DellPowerTrigger repository on GitHub, at the commit this page was made from: the board is src/DellPowerTrigger.kicad_pcb and its schematic src/DellPowerTrigger.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the DellPowerTrigger design in my own project?
Its repository states no licence, so its author keeps all rights: ask medo64 before reusing the design.
