Description

Development board based on the RP2350B microcontroller, designed for developing and testing advanced embedded applications, user interfaces, and multimedia systems. The integrated 3.49-inch IPS capacitive touch display with a 172 x 640 resolution enables the creation of clear, vertically oriented user interfaces without the need for external display modules.

                                                     p1202683-1zdj.jpg

The RP2350B microcontroller features a unique dual-core, dual-architecture design, allowing operation with either two ARM Cortex-M33 cores or two Hazard3 RISC-V cores, with a clock frequency of up to 150 MHz. This approach enables flexible architecture selection depending on project requirements and allows experimentation with the RISC-V platform in a stable hardware environment.

                                                       p1202683-RP2350-Touch-LCD-3.49-details-3.jpg

The board integrates the AXS15231B LCD and touch controller, communicating via QSPI and I2C interfaces respectively, as well as an audio codec, microphone, TF card slot, 6-axis IMU, RTC chip, and an extensive set of communication interfaces and GPIOs. Support for low-power operating modes, drag-and-drop programming via USB, and compatibility with C/C++, MicroPython, and Arduino IDE make the board suitable for educational, prototyping, and product-oriented applications.

                                                       p1202683-RP2350-Touch-LCD-3.49-details-7.jpg

The availability of numerous GPIO pins, SPI, I2C, UART, USB interfaces, and ADC and PWM channels enables easy integration with external modules and expansion of system functionality.
