A combination of DaveM's Stream Cheap Mini Macro Keyboard and Seytonic's Arduino BadUSB with microSD support. This isn't intended to be used as a BadUSB, but as a scriptable macro keyboard (think Zoom mute, music control, etc.).

Code on GitHub

See GitHub readme for links to more details and limitations.

Materials

• Sparkfun Pro Micro board (Sparkfun, Amazon (clone))
