Wave 1.69" Touch Display Pi RP2040

The Wave 1.69" Touch Display Pi RP2040 is a feature-packed microcontroller development board designed by Waveshare. It combines the powerful RP2040 chip from Raspberry Pi with a vibrant 1.69-inch capacitive touch IPS display offering a 240×280 resolution and 262K colors. With rounded corners and a compact design, it’s perfect for modern, portable applications. The board includes a 6-axis IMU sensor (3-axis accelerometer and gyroscope), a real-time clock (RTC), a buzzer, and a Li-ion battery recharge manager, making it ideal for projects that require mobility, precision, and multimedia functionality.



This dual-core ARM Cortex M0+ processor operates at up to 133 MHz and offers 264KB SRAM, 16MB Flash, and versatile connectivity via USB Type-C. The board is easy to program with drag-and-drop functionality and supports low-power modes for energy-efficient applications. Whether for wearable devices, IoT, or embedded systems, this board offers exceptional flexibility and integration options.
