This thing is awesome. And confusing. For the price you get a Mega, and an ESP 8266 in one package. And I can quite easily program either of them after looking up the dip switch config online... Getting them talking to each other has been a little more difficult. Though i've made progress in that I can get the ESP talking to serial while the mega is controlling an lcd display. Havn't spent enough time yet on this to get much farther. I got two of them. Both arrived well, and work great. One of them I've temporarily left in a state of being an ultrasonic type of radar... Thats right. A simple RADUSSS. It displays on the TFT touch screen shield they sell on here as well. Once I get the esp involved, hopefully, i'll be able to do things like create a dynamic website that displays the RADUSSS output and maybe even lets me adjust servo speed etc... All in all, even if you just need a Mega, the esp is nice. And potentially getting the wifi working with a mega makes this a great cost effective package. Good luck.
