* The bottom silk screen has been cleaned up and added to the gerber file set. Minimig rev1.1 is 100% core and firmware compatible with the rev1.0 PCB. Although it has not been built by me (and therefore has not been verified by me), it passes all design rule checks so I trust it will work. The rev1.1 PCB (like rev1.0) has been designed using rather "relaxed" design rules so any PCB manufacturer should be able to produce it.

  • The wire patch needed for rev1.0 to work is now incorporated into the layout. So, rev1.1 doesn't need a single wire patch.
Pin FPGA Name v1.0 Assignment v1.1 Assignment Comment
19 IO_7 User3 SPI_DOUT
79 IO_4/GCLK0 RAM_A15 RAM_A15
81 IO_4/DOUT SPI_DOUT NC
Spare I/O (J9), User3 has been replaced with SPI_DOUT.
  • SD/MMC: R49 has been decreased from 1000Ω to 100Ω for better MMC-Card compatibility.
J11 - SD Card slot
  • The PS/2 connectors are now properly connected to the frame ground.
J5 - pin7,pin8,pin9 wired to "FRAME1"
J8 - pin7,pin8,pin9 wired to "FRAME1"
  • The bottom silk screen has been cleaned up and added to the gerber file set. Minimig rev1.1 is 100% core and firmware compatible with the rev1.0 PCB.
