Waveshare RP2040 Camera Dev Board w/ HM01B0 Grayscale Sensor & 1.14-Inch IPS LCD

The board supports drag-and-drop programming via its USB Type-C port. Connect it to your computer, and it will appear as a mass storage device. Simply drag your compiled UF2 firmware file onto this drive to flash it. You can develop code using the Arduino IDE with the Raspberry Pi Pico core, MicroPython, or the official C/C++ SDK (RP2040 SDK). The onboard 16MB flash provides ample space for your application and stored images.

The HM01B0 grayscale camera communicates over an SPI interface. You will need to use libraries or write code to configure the sensor's registers, trigger captures, and read out the pixel data. Example code is often available from Waveshare or the Raspberry Pi Pico community. The RP2040's PIO blocks can be leveraged to handle the precise timing required for the camera's data clock, freeing up the main CPU cores for image processing tasks on the captured monochrome frames.

Yes, the 1.14-inch IPS LCD, driven by the ST7789V controller, can be used independently. You can display graphics, text, sensor readings, or UI elements using standard display libraries compatible with the ST7789. The display typically uses an SPI interface. You must manage the shared GPIO pins if using both the camera and display simultaneously to avoid conflicts, ensuring proper chip select (CS) lines are toggled for each peripheral during communication.

The board operates at 3.3V, which can be supplied via the USB Type-C port. The RP2040 microcontroller features low-power sleep and dormant modes, which can significantly reduce current consumption when the camera and display are not actively in use. You can put the core into sleep while keeping certain peripherals active, or use deep sleep modes for battery-powered applications, waking via a timer or external interrupt to capture periodic images or sensor data.
