Looking at your NodeMCU knock-off board from China or elsewhere, you can find pin D0 and pin D3, but where's pin D1??

Look closely! You've come across one of these odd boards where the printed numbering has two D2 pins! See? You've got D0, then D2, then D2, then D3, D4 ...

D2 twice isn't twice the fun, but merely means that the first pin D2 is D1 of course...

I'm tinkering here with a NodeMCU ESP8266 board.
I'm using the ESP8266 Java IDE ESPlorer.
The firmware is version 0.9.6 build 20150704 powered by Lua 5.1.4
