Nice piece of ESP32

It's a nice board. Well made, you'll need to solder in the headers yourself if you need those. Antenna was a bit fiddly to get in but the connection is solid. It runs Arduino code (you'll need to add the ESP32 family to the Arduino IDE via a json download), pure c/c++ via the ESP-IDF and make or cmake, and others. Very interesting is the FreeRTOS option - split up your Arduino style code into individual vTasks and you can schedule these to run e.g. every 100ms or ever second or minute or hour. It has a real-time clock which can sync to an NTP server via WiFi - not sure if the RTC maintains the date/time when powered off, I doubt it does.
Unit comes with zero documentation, and webshop has no docs either, so you'll need to g00gle or b!ng your way around to get those of the web. Espressif's is probably a good starting point. Let's hack this thing.
