RipDraw 1U SPI to Beagle Bone Black Cable Notes (Private Notes)


  1. The RipDraw 1U SPI to Beagle Bone Black should be made with mating connector to RipDraw 1U CON 5
  2. The other end will be two sets of flying leads
  3. One set of flying leads is for the connection to the BBB (pins on BBB are too far apart for a connector)
  4. The other set of flying leads allow for a T connection for a SPI sniffer (flying leads allow for different sniffers)
  5. The flying leads should be female with 29 AWG wire. (female is electrically safer and user can convert)
  6. Length cable should be about 6 inches.
  7. Use the color coding in table for signals
  8. Provide an ADDITIONAL flying lead for GROUND
  9. Total number of flying leads will be 11, (5 x 2) plus additional ground lead.
