I've ordered a current parts kit but have acquired some v2.2 boards - apart from P3 which I wouldn't use anyway, and the layout changes which sound minor, are there any BOM changes or will the parts kit work OK with v2.2?

Thanks.

We don't have great information records for previous board revisions, I believe the V3 boards only functionally changed by adding P3. However importantly for you, I think they switched to using the article part numbering instead of BOM part numbering, so please do double check everything. Measure twice cut once and all that...
