Soldered Inkplate is a solid option for anyone wanting a device with Wi-Fi, backlight, touch screen, battery, and runs arduino or micro python. Recently set one up as a display that updates if I'm in a meeting or free that I hang on my office door.

Also shout out to https://usetrmnl.com/ which is much cheaper than OP if all you need is a display that updates every 5+ minutes. The founder is a really cool guy and cares a lot about this project
