Seems like the only place to get them soon with be on the Onion store - Mouser has them as EoL as well: https://www.mouser.com/ProductDetail/Onion/OM-E-RLY?qs=%2Fha2pyFaduh1XVVaqBUS1j5dk5TfvQizQYRoRl5k6D8%3D

Hopefully this isn’t cause for any concern about their general availability.

I just received an email from DigiKey saying that the Relay Expansion is now obsolete - with no replacement. I can’t find any indication of this anywhere on the site, has anyone else gotten this email?
