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