Ardunio: How can I use NodeMCU? Is this Ardunio variant? Can you help about this?
no it is not ardunio variant. but it is controller like ardunio. You can program NodeMcu with Ardunio ide. It has wireless adaptor integrated and this is big advantage.
Not NoneMCU it is NodeMCU
You can buy NodeMcu instead of Ardunio Nano. There is little cost difference but you can control NodeMcu with your phone. If you want to control Ardunio nano with phone or tablet you need extra wifi module.
I suggest NodeMCU modules with c1202 chips because you may experience connection problems with ch340 chips
Code uploading to this card is a bit slower than ardunio
