Description Waveshare 1.8inch colorful display module for micro:bit 160x128 is a compact TFT display expansion module for micro:bit designed to add real-time visual output to projects that go beyond the built-in 5×5 LED matrix. With a 1.8 inch display, 160×128 resolution, and 65K color support, it is a strong fit for interactive demos, educational interfaces, mini dashboards, games, and sensor visualization. This 1.8inch LCD for micro:bit uses the ST7735S display driver and integrates 23LC1024 SRAM as a display cache, helping avoid out-of-memory issues during graphics work. It connects directly through the micro:bit edge connector, uses an SPI interface, supports PWM backlight adjustment, and also reserves solder pads that make it easier to connect with Arduino or Nucleo boards.
