Custom Card Dev : Mapper Footprint ?

Hi all !
After having finaly done a successfull mapper on a breadboard only with somes logics IC and a 4MBit Sram, I wanted to do a prototype PCB using a STM32 in order to load rom by USB. I wrote the schematic in kicad, then realised that it will be realy useless to implement by a fat unhealthy hardware. Maybe just to say : "I did it.". So my goal now is much simpler, building a 512k with two SRAM, one for the rom and the other for the on-board ram, with the 315-5235 Mapper, and ofc a stm32 (and why not an sdcard slot :) ) Here is my point : Some body have the footprint of the 315-5235 for KiCad ? Or at least, I didn't have one, but somebody can take measurement for me ? It seems to be a different proprietary DIP format. Thanks in advance, and Ill show you all advance in my project ! |

Gerry_MAN has a library available for Eagle that includes the 315-5235: http://www.digital-circuitry.com/GameGear_512KB.htm <-- you can grab it there from the "-=My Eagle Schematic Design & PCB Layout=-" section. There seem to be eagle library -> kicad converters out there, but I've never used one so can't vouch for any.
Also attaching a screenshot from the library showing both DIP packages it comes in including scale if that's enough. Curious to see what you come up with. |

Excelent, even if I fail converting it for KiCad, you just give me all quotes, so Ill be able to create the footprint anyway.
Thank you very much ! |
