In case anyone follows the review back to https://www.crowdsupply.com/tall-dog-electronics/tinynes - I've been waiting since the beginning of the year for an update on an order (despite an order ID and emailing multiple times).

I don't think they still exist? Sounds like it used to be cool tech though.

Crowd Supply (Mouser) is backordered, but they’re getting units this month!

Feel free to contact me directly dan@tall-dog.com and I’ll get you sorted out
