LaskaKit 2.7" 400x240 LCD Memory display

Product detailed description

MemoryLCD from Sharp is a very popular display unit because it has very good contrast and at the same time very low consumption. You will find a 2.7" display with a resolution of 400×240 px on our module. The new v1.2 board version adds a µŠup-SPI connector, allowing you to connect the display with a single locking cable, without soldering or searching for the correct wires. If preferred, the classic pin header with SPI bus and power supply can still be used. The MemoryLCD requires two supply voltages, 3.3 V and 5 V. 5 V is generated from 3.3 V via a step-up converter mounted on the board, so in your application, you only need to connect the SPI bus (MOSI, SCK, CS) and power (3.3 V and GND). Power consumption in static mode is 50 µW, and less than 175 µW during rewrite.

Due to its specific hardware architecture, the choice of the specific board model is important. The display operates in "write-only" mode (data can only be written to it, not read back). To render shapes, graphics, or text on the screen, a complete copy of the image (so-called framebuffer) must be created in the microcontroller's operating memory (RAM). Due to the high resolution of 400×240 pixels, this buffer requires approximately 12 kB (11.7 kB) of free RAM.
