Here's the assembly guide and schematic.

This is the new DC28 v2 variant. For the original DC27 AOA, see here. For a fully assembled version, see here.

  • We've gone digital - powered by WP CHIP advanced AOA logic!
    • Still more reliable than Boeing equipment as shipped
  • We've gone to 11 on the LEDs - one more than the previous model
  • Configurable display programs and speeds with rear-mounted variable resistors
    • Flashing your warnings in style
  • Comes in pieces - enough to build 2 indicators!


This is an INTERMEDIATE / ADVANCED KIT. Do NOT purchase unless you are familiar with soldering 0603 SMD components in tight spaces. Do NOT purchase unless you have good iron pressure control.


Kit includes:

  • 2x AOA DISAGREE PCBs
  • 2x WP CHIP digital logic
  • 2x capacitors
  • 6x resistors
  • 4x dual male pin headers
  • 25x LEDs
