WeMos D1 Mini OLED Shield

The WeMos Mini D1 OLED shield is a tiny 0.66″ 64 x 48-pixel OLED display. Using OLED display technology means that not only is the display very bright and clear with a high contrast ratio, but it has a much lower power consumption when compared to other display technologies such as backlit LCD. It is also evident in both total darkness and bright light conditions.

To interface to the module, the display uses a serial I2C interface requiring just two data pins. On-board reset circuitry means there is no need for an additional reset pin.

Although this module is designed to be used with the WeMos D1 mini and mini Pro boards, it is an OLED display with the commonly used SSD1306 display controller and so can be used as a display module with other microcontroller boards such as the Arduino.

The module also includes 2 x 8 pin male-male headers, 2 x 8 pin male-female headers, and two eight pins extended male to female headers (require soldering) that allow the module to be easily inserted into the WeMos D1 mini headers.

Notes:

1. There may be slight size deviations due to manual measurement, different measuring methods and tools.
2. The picture may not reflect the actual colour of the item because of different photographing light, angles and display monitors.
