```Jonty commented on Oct 23, 2020 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. ``` from
