Yes I saw that too, but I assumed it included an emonSD@£9 and a case with the 2x 6pin headers like my example. That would be about £25 quid’ish.
I also noticed that some emonESP and Zero entries did not have a “USB” listed which I’m assuming is the PSU that is required for all emonESP and Zero based emonTx installs, but I haven’t had chance to check the shop pricing to see if it’s missing from the calcs or just a typo in the description.
I think there is also a place for the emonBase (minus the rfm69pi) with a serially connected emonTx as per the Confused Newbie - #5 by pb66 thread.
