WeMos/Lolin 128x64 IIC I2C OLED Module (HCWEMO0019)

***COMMING SOON***

The Wemos/Lolin OLED module is a tiny 128x64 pixel low power OLED display with a screen size measuring just 0.96". It is based on the common and well supported SSD1306 controller and uses an I2C interface (default address = 0x3D) for communication. It is primarily intended for use with Wemos/Lolin development boards, in particular Wemos D1 mini boards that feature the Lolin I2C port header.

PLEASE NOTE: To connect this module to a development board you will need a Wemos SHT1.0 JST 4 pin cable which is sold separately to this display. See Hobby Components item SKU: HCWEMO0020
