With the capabilities 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.\u003c\/p\u003e\n\u003cp\u003eIn addition, it carries two extra onboard sensors. One of them is a digital microphone created through Pulse Density Modulation(PDM) module on the nRF52840 chip. It can receive audio data in real-time which allows it can be used for audio recognition. The board not only receives audio data but also can speak through the MSM261D3526H1CPM microphone. The other one is 6-axis Inertial Measurement Unit(IMU) which can be applied in TinyML projects like gesture recognition. These onboard sensors provide a great convenience for users and the ultra-small size feature of the board has still remained.\u003c\/p\u003e\n\u003cp\u003eSame as \u003ca href=\"\/en-eu\/products\/seeed-xiao-ble-nrf52840-supports-arduino-micropython-bluetooth5-0-with-onboard-antenna\" target=\"_blank\"\u003eXIAO BLE\u003c\/a\u003e, Seeed XIAO BLE Sense contains a wealthy 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.
