This is a 1.8” graphic LCD add-on for the micro:bit. The resolution on the display is 160x128pixels and is capable of displaying 65K colors. This add-on uses the 23LC1024 SRAM which is used as a display cache limiting the “no more memory” problem. The display uses the SPI interface which greatly reduces the amount of I/O required. The backlight is also adjustable using PWM.
