RP2040 1.69 Inch Touch LCD Display Square

This compact 1.69-inch touch LCD display, based on the powerful RP2040 microcontroller, is ideal for developers seeking a user-friendly and versatile display for their projects. With its dual-core ARM Cortex M0+ processor, it achieves clock speeds of up to 133 MHz and offers ample space for applications with 16 MB flash memory. The IPS display with a resolution of 240 x 280 pixels and 262K colors ensures clear and vibrant representations. With the built-in 6-axis motion sensor (3-axis accelerometer and 3-axis gyroscope) and its own real-time clock chip (RTC), the module allows versatile use in smart devices that require precise time and motion processing. Additionally, it features a type-C connector, low power consumption mode, and USB support for host and device applications. The simple programming through drag-and-drop via USB as well as support for C/C++, MicroPython, and Arduino make it an ideal choice for beginners and professionals.
