2. The output is selectable 3.3VDC or 0Vl. Is that user selectable or programmed, and can the output handle it if I am grounding 12 VDC relays to 0Vl to activate them?
PS: Sorry, everyone's a critic, so my two cents is that the Mouser BOM is so cheap compared to the shipping that you could make it more convenient if you offer the parts for purchase, just like you offer the switches. I would pay $6 to you rather than $8 to Mouser and usps for a $2 BOM.
