{"product_id":"round-display-for-seeed-studio-xiao","title":"Round Display for Seeed Studio XIAO","description":"\u003cp\u003eRound Display for Seeed Studio XIAO is a capacitive touch screen expansion board with a 1.28\" circular display, offering 240x240 resolution and 65K colors in a watch-sized 39mm design suited to wearable and space-limited projects. It's built for a wide range of uses, from displaying sensor data to building interactive interfaces, and integrates directly with any XIAO board.\u003c\/p\u003e\n\u003ch2\u003e1.28\" Round Touch Display\u003c\/h2\u003e\n\u003cp\u003eThe onboard capacitive touch screen is a 1.28\" round TFT LCD using the GC9A01 driver chip over SPI, offering a 240x240 resolution with 65K colors and a 100Hz sample rate, giving clear, colourful output in a compact circular form factor well suited to watch faces and other round-display projects.\u003c\/p\u003e\n\u003ch2\u003eRich Onboard Peripherals\u003c\/h2\u003e\n\u003cp\u003eAlongside the display, the board includes a real-time clock with its own battery holder for accurate timekeeping, a battery charge chip for powering the board from a lithium battery, and a TF card slot for expanding memory up to 32GB FAT.\u003c\/p\u003e\n\u003ch2\u003eWatch-Sized and Plug-and-Play\u003c\/h2\u003e\n\u003cp\u003eAt just 39mm across, the board is small enough for wearable and space-constrained builds. All pins are led out, so no soldering is required to get it running with your XIAO board.\u003c\/p\u003e\n\u003ch2\u003eHigh Compatibility\u003c\/h2\u003e\n\u003cp\u003eThe board is designed to work with the full XIAO series. Note that it isn't directly compatible with the XIAO nRF54L15 series, since Arduino isn't currently supported on that board. The hardware interface itself is fully compatible, so developers can manually adapt the software if needed, and official software support from Seeed Studio is in development.\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@35mA via USB Type-C, 3.7V@37mA via battery\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eBattery Connector\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.7V Li-ion battery, JST 1.25 connector\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCharge Current\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e~485mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRTC Chip\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003ePCF8563\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRTC Battery Holder\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eCR927\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eExpandable Memory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eTF card slot, up to 32GB FAT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eScreen\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1.28\" round TFT LCD, GC9A01 driver, 240x240 resolution, 65K colors\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eSample Rate\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e100Hz\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e43mm x 43mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eHardware Overview\u003c\/h2\u003e\n\u003cdiv style=\"text-align: center;\"\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/1_87_1024x1024.webp\" alt=\"Round Display for Seeed Studio XIAO hardware overview\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/files.seeedstudio.com\/wiki\/round_display_for_xiao\/Round-Display-shell-3D-Model.stl\"\u003e3D Printable Shell Model (STL)\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/charge-IC-datasheet.pdf\"\u003eETA6003 Charger IC Datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/ETA3410-datasheet.pdf\"\u003eETA3410 Datasheet\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/RTC-PCF8563-datasheet.pdf\"\u003ePCF8563 RTC Datasheet\u003c\/a\u003e\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":55998632427812,"sku":"SS104030087","price":39.6,"currency_code":"AUD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/2-104030087-seeed-studio-round-display-for-xiao-new-45font.jpg?v=1786275490","url":"https:\/\/zaitronics.com.au\/products\/round-display-for-seeed-studio-xiao","provider":"Zaitronics","version":"1.0","type":"link"}
