This listing is for one black FlashFloppy-firmware-enabled (pre-flashed, FW Rev. 3.28) Gotek floppy drive emulator, which includes an OLED screen and Rotary encoder knob/selector. This version of GOTEK is based on an Artery ARM Cortex-M4 MCU, which FlashFloppy firmware introduced support for in version 3.26. The OLED and rotary encoders are factory-installed.
This floppy emulator is capable of replacing internal 3.5" floppy drives on Amiga, Atari ST, PC compatible, and many other floppy drive systems. It runs highly configurable, open source firmware. Search for "FlashFloppy FF.CFG" for further details on configuring it for your use case.
