Q: Hello A.R Can you confirm this ESP8266 Dev board will work with Arduino IDE (+ Blynk ) out of the box ? I have had hard time with ESP8266-01 to get work with Arduino IDE, worked in LUA and AT command mode but no luck with Arduino IDE ( Blynk IoT examples ). I mean, without any firmware update/change ? Please check and confirm. If it is confirmed I will buy this. Questioned by suntop, 26-May-2018
