This is just the regular NodeMCU with the OLED 1306 display attached to it. That saves the hassle of attaching the display. The length of the print is a bit longer than the normal NodeMCU boards, but it still fits inside the plastic housing (article 1063302 ) as shown on the photos. The display is not at the same level as the metal cap over the ESP chip, which makes it a bit harder to fit nice inside a box, since the display will not touch the front panel of the box. (see photo) Please note that de pins of the I2C controller of the display are swapped compared to the default setting of the ESP Easy firmware. At least the pins are printed on the PCB. I2C address is 0x3c (default for these displays) ESP Chip ID: 0xED9D4 Flash Chip ID: 0x1640C8 (4MB) USB Chip driver: Silicon Labs CP210x

To help others: when programming thru the arduino ide, connect as WeMOs D1 R2 & mini When initialising the display use SSD1306 display(0x3c, D1, D2); (The default examples use D0 and D2)
