It runs an ARM Cortex-M4 with FPU at up to 64 MHz and is supported by Arduino, CircuitPython, and MicroPython, making it a solid choice for both wireless prototyping and low-power embedded projects.\u003c\/p\u003e\n\n\u003ch2\u003eWireless Connectivity and Low Power Design\u003c\/h2\u003e\n\u003cp\u003eThe board includes Bluetooth Low Energy 5.4 with an onboard antenna, along with NFC connectivity, all in a single compact module. Power design is equally considered, with deep sleep consumption as low as 5 μA and built-in lithium battery charge management, making it well suited to battery-powered and wearable applications.\u003c\/p\u003e\n\n\u003ch2\u003eThumb-Sized and Production-Ready\u003c\/h2\u003e\n\u003cp\u003eAt 21 x 17.8mm, it keeps the classic XIAO footprint, and its breadboard-friendly SMD design with no components on the back makes it easy to work with on the bench or integrate into a finished product.\u003c\/p\u003e\n\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\u003eProcessor\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eNordic nRF52840, ARM Cortex-M4 with FPU, up to 64 MHz\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eWireless\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBluetooth Low Energy 5.4, Bluetooth Mesh, NFC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOn-chip Memory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1MB flash, 256KB RAM\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOnboard Memory\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2MB QSPI flash\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eInterface\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1x UART, 1x I2C, 1x SPI, 1x NFC, 1x SWD, 11x GPIO (PWM), 6x ADC\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e21 x 17.8mm\u003c\/td\u003e\n\u003c\/tr\u003e\n    \u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePower\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e3.3V@200mA operating, 50mA\/100mA charging current, 5V via Type-C, 3.7V via BAT, 5 μA standby\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/tbody\u003e\n\u003c\/table\u003e\n\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\/1_53.webp?v=1786006205\" alt=\"Seeed Studio XIAO nRF52840 Pinout\" style=\"margin-bottom: 16px; float: none;\"\u003e\u003c\/div\u003e\n\n\u003ch2\u003eResources\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003ca href=\"https:\/\/wiki.seeedstudio.com\/XIAO_BLE\/#resources\"\u003eSeeed Studio Wiki\u003c\/a\u003e, full setup guides, pinout diagrams, and project examples\u003c\/li\u003e\n  \u003cli\u003e\u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0870\/0021\/9940\/files\/nRF52840_PS_v1.11.pdf\"\u003enRF52840 Datasheet\u003c\/a\u003e\u003c\/li\u003e\n  \u003cli\u003eBrowse our full range of \u003ca href=\"https:\/\/zaitronics.com.au\/collections\/seeed-studio-xiao-expansion-breakout-boards\"\u003eXIAO Expansion \u0026amp; Breakout Boards\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003ePrefer plug-and-play?
