I have 5 SSR4 v2 boards .... was planning on building them soon.
So this thread was very helpful to find, as I had bought two legacy SSR4 v2 (Blue) transformers and then bought 3 more on mouser SSR4 BOM thinking it was for the v2, but it was for the new v3 (just labeled as v2 on mouser bom). I notice now that the legs on the new v3 transformers are in a different pattern on the new v3 transformers.
This is when I started to scratch my head and get a little concerned.
So I have 3 of the (v3?) transformers which do not fit my SSR4 v2 boards. If I buy the ssr V3 boards, they will fit the new transformers, correct?
Also, the picture in the store of the ssr v3 board appears to be a v2 board ? ... because the transformer pins looks like the old not the new. This is all very confusing.
So what is shown in the store:
picture of ssr4 v3 board -----(is actually)-----> a ssr4 v2 board ?
And what is listed under the wiki BOM for the SSR4 [ doesn't mentioned v2 or v3 ] -----(is actually)-----> the SSR4 v3 BOM, but just mislabled as v2 on mouser still ?
So there is also a mention of the voltage regulator changing for the v3 ... so I apparently ordered (5) of whats on the current ssr4 mouser BOM (5/2012) ... part 821-TS2940CZ50
and I'm wondering what the older ssr3 part# for the OLD regulator was (since it apparently changed and I have 2 of those V2's) Do I have the correct parts to build even a couple SSR4 v2(s) at this point?
Any help appreciate. I'm thinking I could go to the store and order (3) ssr4 v3 pcbs ... and perhaps a couple of the old voltage regulators (if they changed) to complete the (2) ssr4 v2(s) I have parts for.
Sorry for the long rambling post.
