Moreover, Seeed Studio XIAO nRF52840 supports the USB Type-C interface which can supply power and download code. It also has rich On-chip Memory of 1 MB flash and 256 kB RAM, and an Onboard Memory of 2 MB QSPI flash. There are 11 digital i\/o that can be used as PWM pins and 6 analog i\/o that can be used as ADC pins. It supports UART, IIC, and SPI all three common serial ports. 1 Reset button, 1 3-in-one LED, 1 Charge LED, and 1 Bluetooth antenna are on board, allowing developers to debug their code very easily.\n\u003c\/p\u003e\n\u003cp\u003e\n The powerful performance makes it perfect for machine learning applications, and the tiny size allows it to be used in wearable devices and Internet of Things projects, not just for prototypes but the mass production. Furthermore, Seeed Studio XIAO nRF52840 is friendly to the communities for its strong software compatibilities, which supports Arduino, Micropython, and CircuitPython. Except for the software, flexible I\/O allows it to speak to almost any external device.\n\u003c\/p\u003e\n\u003ch2 dir=\"ltr\"\u003e\n Specification\n\u003c\/h2\u003e\n\u003cp\u003e\n To better support IoT and TinyML AI projects, there is an advanced version \"Seeed Studio XIAO nRF52840 Sense\" that carries an extra\n \u003cstrong\u003e\n  6-axis IMU and a PDM microphone.\n \u003c\/strong\u003e\n\u003c\/p\u003e\n\u003cdiv align=\"left\" dir=\"ltr\" style=\"overflow-x:auto;max-width:100%\"\u003e\n \u003ctable border=\"0\" cellpadding=\"0\" cellspacing=\"0\" data-style=\"width: 1351px;
