Simple: what is the actual size of the DC jack on the expansion board for NodeMCU 12E? I measured myself and its outer diameter is 5.5mm but a 5mm plug from a taffware yery0910 could fit inside it. I’m asking this as to find the right breakout barrel plug for said jack…
There are lots of different styles of ESP8266 dev boards, and accompanying breakout boards.

how is it related to Blynk?
