Review on 📚 HiLetgo 5pcs Micro SD TF Card Adapter Reader Module with 6Pin SPI Interface for Arduino UNO R3 MEGA 2560 Due by Rob Allen

Confirmed to work with ESP 12-E. The pin connections are as follows (left = SD module pin, right = ESP 12-E pin): CS => D8SCK => D5MOSI => D7MISO => D6VCC => Vin (*5v, not 3.3v ) GND => GDN that VCC must be connected to 5V Vin for the module to work (when powered from the USB connector). The NodeMCU documentation says 3.3V, which doesn't seem to be true for this module since the module has a built in voltage regulator that only accepts 5V input. Another thing to note is the example sketches for ESP8266/Example . /SD does not use the correct CS output (recommended by NodeMCU) in the SD.begin() function and you need to change this line to SD.begin(15) for it to work.
