Overview

The HM01B0-UPD-EVN is an expansion shield designed for the UPduino board featuring the Lattice iCE40UP5K FPGA. It combines a low-power image sensor with dual digital microphones to enable development of vision and voice-based AI applications at the edge. The board is specifically tailored for ultra-low power machine learning tasks such as person detection or gesture recognition.

Why Choose This Part

This shield leverages the iCE40UP5K FPGA's hardware DSP blocks and integrated RAM to perform efficient signal processing with minimal power draw. The inclusion of both optical and acoustic sensors on a single platform allows for multi-modal sensor fusion in a compact form factor.

Applications

Always-on Vision
Utilizing the HM01B0 low-power image sensor for wake-on-motion or occupancy sensing in battery-operated devices.
Voice Activity Detection
Using the two onboard I2S microphones for beamforming or keyword spotting implementations on the FPGA.
Edge AI Prototyping
Development of neural network inference models for image classification and audio processing using the iCE40 UltraPlus architecture.
