Have you ordered one of these, by the way? I'd love to see some high resolution pics and hear a review about its utility as a HW wallet.
No, I ordered other similar ESP32 device but I am to lazy during summertime to load and install firmware with everything else on it and do some testing and reviews.
I was thinking of ordering similar M5Stick device that was much cheaper but it didn't have camera or battery.
This DIY projects are not meant for keeping large amounts of coins, but they are more of better version of wallet than keeping coins on some mobile device.
