Greaseweazle-F7-Plus

My board design for Keir Fraser's Greaseweazle.

The differences between this design and the original F7 are:

  • PCB 80mm x 50mm, KryoFlux form factor.
  • Added stronger buffers for driving 5.25" drives with higher current pull-up resistors.
  • Integrated 5V switching regulator, so only a single 12V supply is required for drives needing both rails.
  • Choice of full-size or micro USB connector.
  • USB ESD (electro-static discharge) protection.
  • Connections for external LEDs, for use if fitting the board in an enclosure.
  • Jumper link to select write protection by default.
  • Jumper link to disconnect WR_GATE for physical hardware level write protection.
