== Summary ==<br />
The 1.8-inch colorful display module is a compact display for the BBC micro:bit with a resolution of 160x128 pixels and 65K colors. It connects directly to the micro:bit edge connector and uses the ST7735S driver chip plus onboard SRAM as a frame buffer.<br />

<br />
== Technical overview ==<br />
* Resolution: 160 x 128 pixels<br />
* Driver: ST7735S<br />
* Color depth: RGB, 65K colors<br />
* Operating voltage: 3.3 V<br />
* Dimensions: 61 mm x 51.5 mm<br />
* Connection: micro:bit edge connector, plug-in directly<br />
* Onboard SRAM (23LC1024) acts as display cache, prevents out-of-memory errors<br />
* SPI interface uses only a few IO pins<br />
* Backlight adjustable via PWM<br />
* Pre-soldered pads allow connection to Arduino/Nucleo boards<br />

== Notes and version constraints ==<br />
* The source does not contain explicit command-line or CLI commands; the 'commands' refer to pin assignments from the pinout table.<br />
* For programming, TypeScript (graphical) and MicroPython are recommended; per the source, only TypeScript demo code is provided for this LCD.<br />
* Two different GitHub packages must be selected correctly depending on the micro:bit version (legacy vs. V2).<br />
* The package installation step requires manually copying the URL into MakeCode; exact steps may be version-sensitive.<br />
* No compatibility details for other microcontrollers despite available solder pads – needs technician confirmation.<br />
