USB-power module

This is a very simple board performing the following functions:

  • USB B socket (main USB (slave) and +5V power)
  • USB A socket (for USB host)
  • Toggle switch for USB host
  • 3.5mm jack for footswitch/gate or other input/output (audio?)
  • Headers to draw +5V directly off the USB power buss.
