From the vendor
This board is perfect for converting just about any effect project to silent relay switching. Small enough to either mount on top of a momentary footswitch (as shown), or simply tuck it some place into the enclosure. Offers True Bypass capability, without the noisy switching POP that is inherent in some high gain effects.
This board offers a combination of SMD and through hole parts to save on space. SMD parts are 0805 size for the resistors and capacitors, and SOD123 for the diodes. Solder paste and hot air makes quick work of mounting these parts, but a soldering iron with a fine tip, and 0.8mm or finer flux core solder (and a steady hand!) will do the job as well. The example shown here was done in our shop, by hand with a soldering iron.
This board is designed to use the Coda bypass scheme. The preprogrammed PIC chip is available here; http://www.deadendfx.com/product/coda-bypass-pic
