Greaseweazle F1 Plus Mini Rev 1.1

Design Files: https://github.com/solarmon/Greaseweazle/tree/main/Greaseweazle%20F1%20Plus%20Mini%20Rev%201.1

This is the most basic F1 Plus model and has the smallest footprint.

Greaseweazle F1 Plus Rev 1.1

Design Files: https://github.com/solarmon/Greaseweazle/tree/main/Greaseweazle%20F1%20Plus%20Rev%201.1

This is the standard F1 Plus model, has a standard footprint but no Track Display features.

Greaseweazle F1 Plus Gotek

Design Files: https://github.com/solarmon/Greaseweazle/tree/main/Greaseweazle%20F1%20Plus%20Gotek%20Rev%201.1

This Greaseweazle board has been designed to re-purpose and fit into an original Gotek case; and to make use of its LEDC68 display as a track display.

It has been designed to sit on top of the floppy drive that is connected to it.

Greaseweazle F1 Plus 3.5"

Design Files: https://github.com/solarmon/Greaseweazle/tree/main/Greaseweazle%20F1%20Plus%203.5%20Rev%201.1

This Greaseweazle board has been designed to have a 3.5" floppy drive mounted directly on top of it, using the floppy drive standard mounting holes.

The track display feature can support the LEDC68 Gotek LED display, or a 128x32 0.91" OLED display, or a 128x64 0.96" OLED display.

Track Display

The GW F1 Plus Gotek/3.5" Track Display is provided by an Arduino Nano. The Arduino sketch for this can be found at:

https://github.com/solarmon/Greaseweazle/tree/main/Arduino_Nano_GW_F1_Plus_Floppy_Drive_Track_Display_LED_and_OLED

The LEDC68 and OLED display adapter board, used in the GW F1 3.5" and GW F1 Plus 3.5" boards, can be found at:
