It's a handy bench tool for anyone prototyping on a breadboard who wants to see what their circuit is actually drawing without reaching for a multimeter.\u003c\/p\u003e\n\u003ch2\u003eReal-Time Power Monitoring\u003c\/h2\u003e\n\u003cp\u003eEssential power metrics are visible at a glance on the built-in LCD, showing live voltage, current, and power data with line charts and statistics. A TI INA3221 triple-channel monitor handles dual-channel voltage and current sensing, so you can track both output rails simultaneously.\u003c\/p\u003e\n\u003ch2\u003eHigh-Current, Dual-Rail Output\u003c\/h2\u003e\n\u003cp\u003ePowerBread delivers up to 1.5A of stable 3.3V power alongside a 5V output, covering most breadboard-based electronics projects in a compact footprint that's designed to minimise space usage on a standard breadboard.\u003c\/p\u003e\n\u003ch2\u003ePlug-and-Play Design\u003c\/h2\u003e\n\u003cp\u003eIt's powered via USB-C through your XIAO board and works straight out of the box on any standard breadboard, with no extra setup required. Long-press the dial to switch between channels in chart and statistic mode, and rotate it to adjust the display for different viewing angles.\u003c\/p\u003e\n\u003ch2\u003eOpen-Source and XIAO Compatible\u003c\/h2\u003e\n\u003cp\u003ePowerBread is compatible with almost all Seeed Studio XIAO dev boards, including the XIAO RP2040, RP2350, ESP32-C3, ESP32-S3, and ESP32-C6, with support for the XIAO SAMD21 and RA4M1 planned. The design and firmware are fully open-source, with active development on new features including PWM generation, ADC reading, and serial monitor functionality.\u003c\/p\u003e\n\u003ch2\u003eXPB Web Console\u003c\/h2\u003e\n\u003cp\u003eThe \u003ca href=\"https:\/\/xiao-power-console-web.ioatlas.com\"\u003eXPB Web Console\u003c\/a\u003e is a free companion browser app that turns PowerBread into a full power-analysis workstation. Plug the board into any Chromium-based browser, click Connect, and the firmware streams live measurements over the Web Serial API, with no drivers or installs required. It includes live charts for voltage, current, and power on both channels sampled at 100 Hz, per-channel energy integration in mAh and mWh with a one-click reset, dark and light themes, and a debug console for troubleshooting.\u003c\/p\u003e\n\u003ch2\u003eWhat's Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eXIAO PowerBread board\u003c\/li\u003e\n\u003cli\u003e2x 2x2 pin headers\u003c\/li\u003e\n\u003cli\u003e1x 2x3 pin header\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003ctable border=\"1\" cellpadding=\"6\" cellspacing=\"0\" style=\"border-collapse: collapse; width: 100%;\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInput Voltage\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePowered via USB-C through the XIAO board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutput Voltages\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5V and 3.3V, up to 1.5A on the 3.3V rail\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDisplay\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eLCD screen for real-time power monitoring\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurrent Sensing\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTI INA3221 triple-channel current\/voltage\/power monitor, dual-channel simultaneous measurement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOnboard Microcontroller\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eRP2040, handles sensor data, display control, and future USB-serial and PWM features\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCompatible XIAO Boards\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eXIAO RP2040, RP2350, ESP32-C3, ESP32-S3, ESP32-C6 (SAMD21 and RA4M1 support coming soon)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePCB Dimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDesigned for seamless breadboard integration with a minimal footprint\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eDisplay Modes\u003c\/h2\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/F1-114993507.webp\" alt=\"XIAO PowerBread monitor, line chart, and statistic modes\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003cp\u003eThe onboard display switches between monitor mode, a live line chart, and a statistics view.\u003c\/p\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/F2-114993507.webp\" alt=\"XIAO PowerBread switching between 3.3V and 5V channels\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003cp\u003eLong-press the dial to switch between the 3.3V and 5V channels.\u003c\/p\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/xiao-power-console-web.ioatlas.com\"\u003eXPB Web Console\u003c\/a\u003e, the companion browser app for live power analysis\u003c\/li\u003e\n\u003cli\u003e\n\u003ca href=\"https:\/\/github.com\/nicho810\/XIAO-PowerBread\"\u003eGitHub Repository\u003c\/a\u003e, open-source firmware and hardware design files\u003c\/li\u003e\n\u003cli\u003eBrowse our full range of \u003ca href=\"https:\/\/zaitronics.com.au\/collections\/seeed-studio-xiao-boards\"\u003eXIAO Development Boards\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Seeed Studio","offers":[{"title":"Default Title","offer_id":55998195990820,"sku":"SS114993507","price":43.0,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/1-114993507-xiao-powerbread-45font.jpg?v=1786250203","url":"https:\/\/zaitronics.com.au\/products\/seeed-studio-xiao-powerbread-breadboard-power-supply-meter","provider":"Zaitronics","version":"1.0","type":"link"}
