Description

This development board is engineered as a comprehensive system-on-module for building advanced human-machine interfaces (HMIs) and smart IoT devices. Its core is the RP2350 microcontroller, which uniquely supports both ARM Cortex-M33 and RISC-V instruction sets across its dual cores, allowing developers to optimize performance and power efficiency for specific tasks. The integrated 3.5-inch IPS capacitive touchscreen provides a responsive and vivid visual output layer, essential for control panels, portable instruments, and interactive kiosks.

Beyond the display, the board consolidates a wide array of industrial-grade peripherals into a compact form factor. The dedicated camera interface enables direct connection to popular image sensors like the OV5640, opening doors for machine vision applications. Integrated power management supports direct Li-ion battery operation and low-power sleep modes, while the onboard 6-axis IMU, audio codec, and real-time clock (RTC) provide essential sensing and timing functions without external wiring. This high level of integration accelerates prototyping and reduces BOM complexity for final product designs.

Key Features

  • High-Resolution Touch Interface: 3.5-inch IPS capacitive touchscreen with 320x480 resolution and 65K colors delivers sharp graphics and intuitive user interaction.
  • Dual-Architecture Processing: Leverage the flexibility of the RP2350's ARM Cortex-M33 and RISC-V cores, clocked at up to 150MHz, for mixed-criticality or performance-optimized firmware.
  • Direct Camera Module Support: Onboard parallel camera interface compatible with OV5640 (5MP) and OV2640 (2MP) sensors for embedded vision projects.
  • Comprehensive Sensor Suite: Built-in 6-axis IMU (accelerometer and gyroscope) and RTC provide motion sensing and precise timekeeping capabilities.
  • Simplified Development Workflow: USB Mass Storage Device (MSD) programming allows for drag-and-drop firmware updates without dedicated programmers.
  • Multimedia-Ready Audio: Integrated low-power audio codec supports both microphone input and speaker output for voice-enabled or audio playback applications.
  • Expandable Storage: Onboard microSD (TF) card slot enables logging of sensor data, images, or firmware updates.
  • Robust Power Management: Circuitry supports USB power, external DC input, and single-cell Li-ion battery charging/discharging with low-power operating modes.

Applications

  • Smart IoT Control Panels: Create interactive dashboards for home automation, industrial monitoring, or agricultural systems.
  • Portable Multimedia Devices: Develop handheld instruments, audio players, or portable gaming consoles with touchscreen UI.
  • Embedded Vision Systems: Build prototypes for security cameras, barcode scanners, or machine vision inspection using the OV5640 interface.
  • Wearable & Fitness Tech: Leverage the IMU and low-power modes for activity trackers, sports watches, or health monitoring devices.
  • Rapid Prototyping Platform: Serve as an all-in-one evaluation board for the RP2350 MCU, testing drivers for display, camera, audio, and sensors.

Frequently Asked Questions

How do I program the Waveshare RP2350 development board?

The board supports drag-and-drop programming via USB Mass Storage Device (MSD). Connect the USB Type-C port to your computer; it will appear as a removable drive. Simply copy your UF2 firmware file to this drive, and the board will automatically reset and run the new program. This method works with the Pico SDK, MicroPython, and CircuitPython, eliminating the need for a separate programmer. Ensure you have the correct UF2 binary for your project.

What camera modules are compatible with the onboard interface?

The development board features a parallel camera interface directly compatible with popular OV series sensors, specifically the OV5640 (5 Megapixel) and OV2640 (2 Megapixel). You can connect these modules via the dedicated connector. Driver support is typically provided through the Pico SDK or community libraries. Ensure your chosen camera module matches the pinout and voltage requirements. This interface enables embedded computer vision applications like object detection or video streaming.

Can I power the board with a battery, and what are the low-power features?

Yes, the board includes integrated power management supporting a single-cell Li-ion battery via its JST connector. It features charging circuitry powered from the USB port. The RP2350 MCU itself supports various low-power sleep modes, which can be leveraged to extend battery life in portable applications. You can monitor battery voltage through an ADC pin. Combine this with the display's backlight control and peripheral power gating in firmware to achieve optimal power efficiency for field-deployed IoT devices.

What development frameworks and IDEs are supported for the RP2350 MCU?

Primary development is supported via the Raspberry Pi Pico SDK (C/C++) and higher-level languages like MicroPython and CircuitPython. You can use Visual Studio Code with PlatformIO, Thonny for MicroPython, or command-line tools with the Pico SDK. The dual-core, dual-architecture design allows you to assign tasks specifically to the ARM Cortex-M33 or the RISC-V core. Community resources and examples are available for accessing the display, IMU, audio codec, and camera peripherals within these frameworks.
