The RP2350 2.1-inch circular touchscreen development board integrates an RGB display interface, an touch interface, and multiple peripheral interfaces. This product is a self-designed, high-performance, and highly integrated microcontroller development board. In a compact form factor, it features a 2.1-inch capacitive high-definition IPS screen, a six- sensor (three- accelerometer and three- gyroscope), an RTC, and a Micro-SD card slot, facilitating development and integration into products. The RP2350B microcontroller chip, designed for , features a dual-core, dual-architecture design, incorporating a dual-core ARM -M33 processor and a dual-core Hazard3 RISC-V processor, both operating at clock frequencies up to 150MHz, allowing users to flexibly switch between the two architectures. It includes 520KB of and 16MB of on-chip Flash, with a reserved PSRAM interface using a Type-C connector, eliminating the need for reversible insertion. It features an onboard 2.1-inch capacitive touchscreen HD IPS display with a 480 x 480 resolution and 65K color depth, capable of clearly displaying color images. It supports USB 1.1 host and slave devices. It supports low-power sleep and hibernation modes. It can be recognized via USB for drag-and-drop program downloading to a mass storage device. Nine versatile GPIO pins are provided. Pinout: 2 SPI, 2 , 2 UART, 5 12-bit ADCs, and 9 controllable PWM channels Precise on-chip clock and Temperature sensor On-chip accelerated floating-point library 12 programmable I/O (PIO) state machines for custom peripheral support Application Scenarios: HMI (Human Machine Interface): A human machine interface (HMI) is the medium for interaction and information exchange between a system and a user. It enables the conversion between the ernal form of information and a human-readable form. LVGL GUI Development: LVGL is a free and open-source graphics library designed for embedded GUIs. It provides easy-to-use graphical elements for displaying beautiful visual effects and features low memory usage. Dual-Core, Dual-Architecture: The RP2350's dual-core, dual-architecture feature allows users to switch between a pair of industry-standard Arm -M33 cores and a pair of open-hardware Hazard3 cores, enabling developers to experiment with the RISC-V architecture in a stable and well-supported environment. Supports C/C++, for MicroPython, and for , with a complete SDK and open-source tutorials for and quick integration into applications.
