Where can i get a Tx4 6CT expansion board? I note from the post What's happened to emonTx V4? - #67 by TrystanLea that the Tx4 is discontinued, but the hardware still has significant life left for those of us willing to use it (mine is only 2 years old!!!), and I can’t understand why i need to buy a whole new £188 Tx5 when the £30 expansion board would be fine, if it was in stock.
I’m happy to build one myself, if that’s what it takes, but it’s not something i’m familiar with, and JLCPCB seems to have issue with a bunch of parts on the BOM.
Are you going to bring the Tx4 expansion back in to stock? Or can you provide updated BOM so that it’s possible for us to order them ourselves?
