ZYPDS voltage output

[Spoonbill-Bazaar]

On the ZYPDS board there are two sets of solder pads, not just what you circled in yellow, but also the two pads to the left of that yellow circle. Bridging both sets results in a voltage of 5v. Bridging the right-most set results in a voltage of 12v. I can de-solder and test the results of just the left-most set of pads but I imagine it will output 9v in that configuration.

Excellent information, thank you! Then what configuration results in the 15V the seller mentions in that picture?

I'd love to document this if we can confirm! Unfortunately my board is packed away right now, so I won't be able to test until later.

There appear to be two different variants of the ZYPDS board - some are sold as 9v/12v, and some as 15v/20v.

I have the 15v/20v models, which are described as "20v / 5v" on the reverse silkscreen, with the placement of the text directly underneath the pads on the flip side that give those voltages. Both sets of pads open results in 20v, right set bridged gives 15v, left set bridged gives 5v, both bridged gives 5v.

I found a specsheet for the IP2721. It describes how to use the select pin to set three voltage.
