Description

This Waveshare development board centers on the Raspberry Pi RP2350B, a unique dual-core, dual-architecture microcontroller capable of running ARM Cortex-M33 or Hazard3 RISC-V cores at up to 150 MHz. It drives a high-quality 2.1-inch round IPS display via an SPI+RGB interface, paired with a capacitive touch panel for intuitive control. The board is engineered for low-power operation, supporting sleep modes to extend battery life in portable and wearable applications.

Beyond the display, the board incorporates a suite of onboard sensors and interfaces critical for embedded systems. The 6-axis IMU provides motion data, while the dedicated RTC maintains accurate timekeeping. A full complement of GPIOs, including SPI, I²C, UART, ADC, and PWM, allows for extensive peripheral expansion. The compact 75x75mm form factor, combined with the integrated flat touch panel, makes it ready for direct integration into final product enclosures for smart watches, industrial dashboards, and automation controllers.

Key Features

  • Dual-core RP2350B microcontroller with ARM Cortex-M33 and Hazard3 RISC-V support for architectural flexibility.
  • High-resolution 2.1-inch round IPS display with capacitive multi-touch for sleek, modern user interfaces.
  • Onboard motion sensing via a 6-axis IMU (3-axis accelerometer + 3-axis gyroscope).
  • Precise timekeeping with the integrated PCF85063 Real-Time Clock (RTC) chip.
  • Expandable storage via a microSD (TF) card slot and 16MB of onboard Flash memory.
  • User-friendly USB Type-C interface supporting PIO-USB and drag-and-drop programming for easy code deployment.
  • Rich I/O including multiple SPI, I²C, UART channels, ADC inputs, and PWM outputs for sensor and actuator connectivity.
  • Compact and robust design with all components on a single board, suitable for space-constrained end products.

Applications

  • Smart wearable devices and fitness trackers with interactive displays.
  • Industrial control panels and human-machine interface (HMI) dashboards.
  • Portable instrumentation and data loggers with sensor visualization.
  • Home automation controllers and smart appliance interfaces.
  • Prototyping compact IoT devices requiring a graphical user interface and motion sensing.

Frequently Asked Questions

How do I program the Waveshare RP2350 development board?

The board is programmed via its USB Type-C port using drag-and-drop firmware updates. Connect it to your computer, and it will appear as a mass storage device. Compile your code into a UF2 file using the Pico SDK, Arduino IDE with Raspberry Pi Pico cores, or MicroPython, then simply drag and drop the file onto the board's drive to flash it. The onboard bootloader and PIO-USB support facilitate this seamless process without an external programmer.

What are the power requirements and sleep current for battery operation?

The board operates at 3.3V, typically supplied via the USB Type-C port. For battery-powered applications, you can connect a 3.3V regulated supply to the appropriate pins. The RP2350B microcontroller supports multiple low-power sleep modes, which can significantly reduce the operating current to microamp levels, extending battery life in portable and wearable projects. Exact sleep currents depend on which peripherals (display, IMU, RTC) remain active.

How do I interface with the capacitive touch screen and onboard IMU sensor?

The capacitive touch panel uses an I²C interface. You can read touch coordinates and gestures via the dedicated touch controller IC using standard I²C libraries. The 6-axis IMU (accelerometer and gyroscope) also communicates over I²C. Example code provided by Waveshare demonstrates how to initialize both sensors and read raw data or fused motion values for your application, compatible with C/C++ (Pico SDK) and MicroPython environments.
