With the capability of wireless connection, it still remains the Seeed XIAO series classic form-factor of small and exquisite which can be used for wearable devices and Internet of Things projects. Furthermore, it only costs 5 μA in the deep sleep model and it supports battery charge management because of the BQ25101 chip. To better support IoT and TinyML AI projects, there is an advanced version \u003ca href=\"\/en-eu\/products\/seeed-xiao-ble-nrf52840-sense\" target=\"_blank\"\u003e\"Seeed XIAO BLE Sense\"\u003c\/a\u003e that carries both 6-axis IMU and PDM microphones.\u003c\/p\u003e\n\u003cp\u003eCompare to \u003ca href=\"\/en-eu\/products\/seeed-xiao-rp2040\" target=\"_blank\"\u003eXIAO RP2040\u003c\/a\u003e, Seeed Studio XIAO nRF52840 has a richer interface. The first thing to note is that the Near Field Communication(NFC) is functional on the board. Secondly, there is a tiny and elegant reset button on one side of the Type-C interface. On the other side, it is designed in a three-in-one LED along with a power LED. 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.
