4.2" AM EPD Display 400×300 | DMAYE04201LNA
The DMAYE04201LNA is a 4.2-inch active matrix electrophoretic display (AM EPD) designed for ESL and other portable, low-power applications. It features a 400×300 resolution with a 0.212 mm pixel pitch in a pure reflective, bi-stable mode for excellent daylight readability and ultra-low power use. The module integrates gate/source buffers, MCU interface, on-chip oscillator, DC-DC, SRAM/LUT, and provides SPI plus an I²C master for external temperature sensing.
