README
README.mdAmiga1200 single power
This is a DCDC converter Module to fit in Rev. 6a+ Amiga 500 mainboards. It will be soldered onto the mainboard and one can then use a 12V barrel jack power supply with the Amiga 500.
It can deliver upto 6A @ 5V and 500mA @ -12V. The 12V line is passed through.
It also adds a power switch to the machine on the backside.
This design has not been finally tested yet.

Questions
How big is the A1200 pwr PCB?
It measures 23.2 × 50.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the A1200 pwr use?
20 parts, built around the LMZM23600SILR, RPM5.0-6.0 and PJ-102A. 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 A1200 pwr KiCad files?
From the MastaTabs/a1200spwr repository on GitHub, at the commit this page was made from: the board is a1200_pwr.kicad_pcb and its schematic a1200_pwr.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the A1200 pwr design in my own project?
Its repository states no licence, so its author keeps all rights: ask MastaTabs before reusing the design.
