Waveshare 33301 RP2350 1.85inch 360×360, 65K Color Round LCD Development Board Standard Version

The RP2350 1.85-inch Round LCD Development Board – Standard Version is a compact yet powerful microcontroller platform designed for modern embedded display applications. Powered by the Raspberry Pi RP2350A microcontroller, it features a unique dual-core and dual-architecture design, allowing developers to work with either ARM Cortex-M33 or Hazard3 RISC-V cores at clock speeds up to 150 MHz. This board integrates a vibrant 1.85-inch capacitive IPS round display with 360×360 resolution and 65K color depth, delivering excellent visual clarity and wide viewing angles. With onboard 16MB flash, RTC chip, TF card slot, audio codec, microphone, and multiple communication interfaces, it significantly reduces external component requirements. USB Type-C ensures easy programming and power delivery, while drag-and-drop USB mass-storage programming simplifies development. Its low-power modes, rich GPIO options, and touch interface make it ideal for interactive embedded products and smart UI designs.
