What I’m looking for is the “ready for pocket” device that has wifi, a screen, and some input like a keyboard. Are there any ESP32 or Teensy kits that yield that kind of thing in a pretty decent, durable result?
You could consider the Keyboard FeatherWing. It contains only the screen and keyboard part. You are meant to add a Feather format board that has a microcontroller and Wi-Fi, for example Adafruit’s ESP32 Feather board.
Thanks!
