Overview
A500 pwr is an open-source printed circuit board by MastaTabs, from the MastaTabs/a500spwr repository on GitHub. It is a 2-layer board of 33.5 × 43.8 mm with 20 parts on 19 nets, routed with 89 tracks and 30 vias.
It is built around the LMZM23600SILT, RPM5.0-6.0 and PJ-102A, with the RMS1R102M7QES among its other parts. Its parts include 7 capacitors, 4 resistors, 3 connectors, 2 ICs and 2 inductors. It belongs with the power and retro computing and games boards of this library.

README
README.mdAmiga500 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.
It has been tested by me and was found to be working good.

Questions
How big is the A500 pwr PCB?
It measures 33.5 × 43.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the A500 pwr use?
20 parts, built around the LMZM23600SILT, RPM5.0-6.0, PJ-102A and RMS1R102M7QES. 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 A500 pwr KiCad files?
From the MastaTabs/a500spwr repository on GitHub, at the commit this page was made from: the board is a500_pwr.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the A500 pwr design in my own project?
Its repository states no licence, so its author keeps all rights: ask MastaTabs before reusing the design.
