General Information

The Bacon Cape is an accessory board design to be used with the BeagleBone Black or original BeagleBone (aka White). The Bacon Cape was designed to provide hardware examples of some of the basic input/output features of the BeagleBone products.

Features

  • PWM controlled Red/Green/Blue LED
  • GPIO Output controlled 7 Segment LED display ( Requires DT overlays pin 87 44e1095c gpio0[4], pin 86 44e10958 gpio0[5])
BBB Header Pin Mem GPIO
P9_17 pin 87 44e1095c gpio0[5]
P9_18 pin 86 44e10958 gpio0[4]
  • ADC input using a variable resistor slider potentiometer
  • GPIO input using a button
