It's a solid base for wearable projects, sensor hubs, and anything that needs onboard debugging without tying up a PC.\u003c\/p\u003e\n\u003ch2\u003eOnboard OLED for Visual Debugging\u003c\/h2\u003e\n\u003cp\u003eThe built-in 0.96\" OLED display lets you view sensor readings, status data, or debug output directly on the board, without needing a serial monitor connected to a PC. That makes it well suited to standalone builds like data monitors or sensor hubs where a screen is genuinely useful.\u003c\/p\u003e\n\u003ch2\u003eRich Onboard Peripherals\u003c\/h2\u003e\n\u003cp\u003eAlongside the display, the board includes a high-precision RTC with battery backup for accurate timekeeping when main power is off, a passive buzzer for simple audio feedback, a dedicated user button in addition to the reset button, and a MicroSD card slot for expanding memory when working with larger CircuitPython libraries.\u003c\/p\u003e\n\u003ch2\u003eQuick Prototyping and Easy Debugging\u003c\/h2\u003e\n\u003cp\u003eA RESET button and an SWD pin broken out to a male header make debugging and firmware flashing straightforward without extra jumper wires. All pins are led out to standard connectors, so wiring sensors or peripherals is plug-and-play rather than requiring any soldering.\u003c\/p\u003e\n\u003ch2\u003eBattery Power and Charging\u003c\/h2\u003e\n\u003cp\u003eA JST 2.0mm LiPo battery connector and onboard battery management system support both USB and battery power, along with onboard recharging. A 5V output is also broken out to a male header for powering servos or 5V sensors directly.\u003c\/p\u003e\n\u003ch2\u003eCompact Size\u003c\/h2\u003e\n\u003cp\u003eAt roughly half the footprint of a Raspberry Pi 4, the board stays compact enough for tiny and wearable projects while still fitting in the full set of onboard peripherals.\u003c\/p\u003e\n\u003cp\u003eNote this board isn't compatible with the XIAO nRF54 or MG24 series.\u003c\/p\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\u003ePower Supply\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e5V DC or 3.7V lithium battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRTC Chip\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePCF8563T\/5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRTC Battery\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCR1220 (not included)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExpandable Memory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\n\u003ca href=\"https:\/\/zaitronics.com.au\/collections\/memory-storage\" title=\"Micro SD Cards\" rel=\"noopener\" target=\"_blank\"\u003eMicroSD card\u003c\/a\u003e slot\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eScreen\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e0.96\" OLED display\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOther Onboard Equipment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePassive buzzer, user button, 5V servo connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCharging Current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eMax 460mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eConnectors\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2x I2C, 1x UART, 1x analog\/digital (A0\/D0)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eIP Rating\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIP40\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003ePinout\u003c\/h2\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/4_26_1024x1024.webp\" alt=\"Seeed Studio Expansion Board Base for XIAO Pinout\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eCompatible with our range of \u003ca href=\"https:\/\/zaitronics.com.au\/collections\/lithium-polymer-lipo-batteries\"\u003eLiPo Batteries\u003c\/a\u003e\n\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":55998618861860,"sku":"SS103030356","price":31.4,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/zheng1.jpg?v=1786273509","url":"https:\/\/zaitronics.com.au\/products\/seeed-studio-expansion-board-base-for-xiao-with-oled-display","provider":"Zaitronics","version":"1.0","type":"link"}
