Waveshare RP2350 Dev Board w/ 1.69-Inch Touch LCD, Accelerometer & Gyroscope

The board supports drag-and-drop programming via its USB Type-C port. When connected to a computer, it enumerates as a mass storage device. You simply compile your code into a UF2 firmware file using supported toolchains like the Raspberry Pi Pico SDK or Arduino Core for RP2040/RP2350, then drag and drop the UF2 file onto the board's removable drive to flash it. No external debugger or special software is required for basic programming.

The RP2350 microcontroller features a unique heterogeneous multi-core design. It contains two independent processor clusters: one with dual Arm Cortex-M33 cores and another with dual RISC-V Hazard3 cores. This allows developers to assign specific tasks to the most suitable architecture. For instance, real-time control or DSP tasks can run on the RISC-V cores, while application logic and communication stacks utilize the Arm cores, enabling optimized performance and efficient power management for complex embedded applications.

Yes, the board includes a Li-ion battery charging and management circuit. You connect a single-cell 3.7V Li-ion or Li-Po battery to the dedicated "BAT+" and "BAT-" headers. The onboard charger manages charging via the USB-C port. The board can operate seamlessly from battery power, and the power path circuitry ensures stable operation even when USB is connected or disconnected. This makes it ideal for developing portable, untethered devices that require occasional recharging.

The 6-axis IMU (Inertial Measurement Unit) is connected to the RP2350 via an I2C interface. To use it, you need to include the appropriate sensor library in your firmware project. You'll initialize the I2C bus on the designated GPIO pins (specifics are in the board's schematic/pinout diagram), then communicate with the sensor using its I2C address to read raw accelerometer and gyroscope data, which can be converted to meaningful units like g-force and degrees per second for your application logic.
