About this item

The Arducam HM01B0 is an ultra-low-power monochrome camera module designed for microcontroller platforms such as the Raspberry Pi RP2040 (e.g., Pico) and Arduino. It features the HM01B0 CMOS image sensor, which outputs QVGA resolution (320x240) images in grayscale, making it ideal for edge AI, machine learning, and low-power embedded vision applications. This camera module stands out for its minimal power consumption, allowing continuous operation on battery-powered devices. It is especially useful for TinyML (Tiny Machine Learning) projects like person detection, gesture recognition, and object classification on microcontrollers with limited memory and processing resources. The HM01B0 supports multiple data output formats (8-bit/16-bit), making it flexible and easy to integrate into various MCU systems. Its compact size and simple interface also make it an excellent choice for DIY electronics, STEM education, and prototyping vision-based smart sensors. The module communicates via parallel bus, and with the help of dedicated libraries and SDKs, it seamlessly integrates with RP2040, Arduino, and other MCU environments. For developers working on AI at the edge, the Arducam HM01B0 offers a lightweight and cost-effective solution to bring vision to microcontroller projects.
