Ditto what @Rppoind said. I also have some projects where these could be used.
Also, I highly recommend reading @Rod Stewart's attached notes in his first post; they are loaded with great information and details about the applications and installations for this board--a trove of useful info.
THANK YOU, Rod.
NOTE: Just ordered your board from OSH Park priced at $2.40 for 3 with free shipping; ordered 6 for $4.80.
