Description
Floppy Disk Drive emulator, OpenFlops (smaller version)
OpenFlops is an Open Hardware Floppy Disk Drive emulator/simulator.
OpenFlops is an Open Hardware implementation of such an emulator, inspired from the ubiquitous Gotek hardware. It is designed to run the FlashFloppy firmware, which gives it several improvements over the original Gotek:
- Can be installed on many different platforms
- Directly supports a wide range of image formats
- Flexible track layout for Raw Sector Images
- Extremely configurable
- Supports AutoSwap for games with a large number of disks
- Easily accessible pin headers for connection of a i2c display (either OLED or LCD), rotary encoder (including power)
- Built-in amplified speaker, or easily-accessible pin header for an external one
- USB connector can either be soldered on the board or connected to a pin header
- Connected Motor signal
- Emulates two drives at the same time (Not yet supported by the firmware, but it will come)
- Has additional 3.3V, 5V and GND power pins

You can download the design files from github and check if they are connected to the same signal.
Ok, on the schematic pins 2,3 and 4 are all on GND, so it's fine.
