Espressif ESP8266 User Manual

D. Wires & Cables
You will also need some wires to connect the display to the ESP8266. In case you want to
connect the display directly to the NodeMCU you will need at least four female-to-female
jumper wires, since both the display and the NodeMCU have male pin headers. The wires
don’t need to be long, 7.87” (20cm) is usually enough.
To program the ESP8266 module you will also need a micro USB cable. In case of the
NodeMCU this cable should have a micro-USB connector on the module side and a normal
USB connector for your PC or Mac.
