The Seeed XIAO PowerBread is an open-source breadboard power supply and monitoring module designed specifically for prototyping with Seeed Studio XIAO development boards(except SAMD21/RA4M1 models). It offers regulated 3.3V and 5V outputs, supports up to 1.5A on the 3.3V rail, and integrates real-time voltage, current, andpower monitoring via an onboard LCD.
Powered via USB-C through the connected XIAO board (not included), the PowerBread uses an INA3221 sensor for dual-channel power monitoring. It also features multiple user interface modes, including live data, charts, and statistics, all visible on the built-in screen. The compact design fits neatly onto a standard breadboard with minimal space usage.
