2.4 TFT Screen 320x240 with Rotary Encoder ST7789

This 2.4-inch colour TFT Screen 320x240 RGB display combines an EC11 rotary encoder with a push switch, and a separate pushbutton on one board. Use it to build menus, adjust settings, or display readings in microcontroller projects.

The display uses an ST7789 driver and communicates over a 4-wire SPI interface. The display has no touchscreen. The display, encoder, and pushbutton have independent interfaces, so your project can use each control as needed.

The EC11 incremental rotary encoder has 20 pulses and 20 detents per revolution, a 15 mm splined shaft with a knob, and a built-in push switch. Its A, B, and PUSH signals are available at the board connector.

The module supports a 3.3 V or 5 V supply, but 5V is recommended because the backlight will be dim at 3.3V.

The board measures 90.8x43.5mm, weighs 33.5g, and has four mounting holes.
