README
README.mdUMDv3
The Universal Mega Dumper v3 project is an open-source solution for cartridge dumping and writing.
This PCB includes a very performant MCU, STM32F407VET6, which is connected to a generalized databus consisting of 24 address bits and 16 data lines. Along with a dozen or so control signals, it should be sufficient to interface with most cartridge types. Each cartridge type requires a separate PCB for interface, please refer to the main project repository for a list of currently available cartridge apdapters.
Project
Please refer to the UMDv3 Firmware Project Repository for UMDv3 documentation and instructions; this is the project's central repository and where the wiki is hosted.

Questions
How big is the UMDv3 PCB?
It measures 147.3 × 83.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UMDv3 use?
68 parts, built around the AZ1117CH-3.3TRG1, 0.1UF 50V 5*11, PTS645SM43SMTR92LFS and 151031VS06000. 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 UMDv3 KiCad files?
From the db-electronics/UMDv3-kicad repository on GitHub, at the commit this page was made from: the board is UMDv3/UMDv3.kicad_pcb and its schematic UMDv3/UMDv3.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UMDv3 design in my own project?
Its repository states no licence, so its author keeps all rights: ask db-electronics before reusing the design.
