ECB Backplane 4

The purpose of this backplane design is to take advantage of the discount offered by many PCB manufacturers with 10x10cm PCB boards. It's a cut down version of A. Lynch and J. Coffman's 8-slot design and was inspired by Will Sowerbutts ECB Mini Backplane board.


  • 4 ECB Slots
  • Low cost 10x10cm format
  • Industry standard power connection
  • On/off switch with LED indicator
  • Reset connector
  • Battery backup connector
  • Additional mounting holes
