1.815”W x 1.11”H

 

2015 change-log: Removed 10R current limiting resistor. 

This PCB is designed for the typical BLUE 3PDT footswitch. Other 

footswitches may or may not fit into the pad spacing allotted. 

Terms of Use: You are free to use purchased 3PRR circuit boards for both DIY and 
small commercial operations. You may not offer 3PRR boards for resale or as part of a 
“kit” in a commercial fashion. Peer to peer re-sale is, of course, okay.
