Do you by chance have a link to a good development kit for the esp32? I checked and I'm a bit overwhelmed by the amount of different components one can get.

- mabcat 7y agoOne that I like is commonly branded TTGO, a search for "esp32 ttgo" or "esp32 oled battery" will turn up some options. This is a link to the exact one I bought since you asked: https://www.ebay.com.au/itm/283082902927 https://www.ebay.com.au/itm/283082902927 (not actually branded TTGO, it's a clone) Why you might like it: - it has an OLED screen on the board for debugging and status output - it has a battery holder and charging circuitry for an 18650 on the back of the board for portable powering/"UPS" - it breaks out all the GPIO lines onto pins Why you might not like it: - like many esp32 dev boards it's slightly too fat to go straight into a standard breadboard. You have to join two breadboards to get access to both rows of pins.
- c22 7y agoLately I've been playing with the Olimex esp32-poe [0]. It supports being powered over ethernet or lipo battery (or micro usb) and includes an SD card slot. If your application uses the ethernet, though, be sure to develop using a non-poe switch (or else power from the ethernet interface can leak over the usb programming interface and damage your laptop.)
