A key feature of the T-Encoder-Pro is its display. It boasts a 1.2-inch AMOLED screen with a resolution of 390 x 390 pixels. AMOLED stands for Active Matrix Organic Light Emitting Diodes, which is a type of screen technology that produces bright and vivid colors. This high-resolution display is driven by the SH8601A-W14-T06 chip, which uses the QSPI bus protocol to communicate with the rest of the device. QSPI, or Quad Serial Peripheral Interface, allows for fast data transfer between the display and the MCU.

LILYGO T-Encoder-Pro Touch and Rotary Encoder

Another interesting feature is the CHSC5816 touch and rotary encoder. This component allows for both touch input and rotation input. The touch input uses the I2C protocol, which is a simple and efficient way to communicate between components. The rotary encoder allows you to rotate left and right, which can be used for scrolling through menus or adjusting settings. This combination of touch and rotation input makes theĀ T-Encoder-Pro very user-friendly and flexible.

Size of LILYGO T-Encoder-Pro
