    Is it a backdoor deal? ;)

  • Are these USB-C, or Micro-USB?

  • Love these boards, even the esp1/esp8266 is crazy cool.

    • What to do with it?

      • run web servers (which i made publicly accessible with pfsense and squid - as i run other servers)and code for learning, bought some components to attach to it, which is fun.

        so my use case is purely educational. (hooking it up to different components etc - given the low power mode, was tempted to make a car GPS tracker as its pretty simple - GPS units are like a few bux)

        only problem is the SIM boards are about 50 bux:
        EG:

  • Does this board support BT A2DP profile?

  • What can a non programmer do with this?

    • Plug it in and watch the led go on and if you are lucky it will flash.
      Learn but I would start with an arduino first, ESP32 can be quite frustrating.

      • I would argue this and say its pretty easy, specially given wifi, bluetooth and USB build in to the ESP32, but now that the Arduinos also have usb to program directly (my original one didn't) and the fact that the Arduino clones are a almost the same price, yeah Arduino is one step down in regards to difficulty, given everything is written for Arduino.

        • It would depend on what you are trying to do and what board, code for ESP32 for one variant may not work the same on another given there so many variants, arduino boards are pretty standard. That's my experience so far. Walk first, run later.
