This is a totally minimalistic case for the ESP8266-12E NodeMCU. It is designed for using the device without pinheaders the possible necessary wires soldered direct to the PCB. There are four holes in the cover to be able to press both buttons with a needle and to see both LED. Especially for IoT-applications the case should be as small as possible. This is the smallest possible one. ;-)
