OLED Shield - (Wemos D1 Mini)

This compact OLED shield is specifically designed for the Wemos D1 Mini board. It features a 0.66-inch graphical display with a resolution of 64x48 pixels, driven by the popular SSD1306 driver IC. It is an excellent choice for adding visual feedback to your IoT or automation projects without consuming excessive GPIO resources.

Connection is made via the I2C interface, using pins D1 (SCL) and D2 (SDA) of the Wemos D1 Mini, leaving other GPIOs available for your sensors and actuators. The display is powered directly from the board's 3.3V rail.
