Development board equipped with Nordic nRF52840 MCU chip, which integrates Bluetooth 5.0 connectivity. Its small dimensions make it suitable for use in wearable devices and IoT projects. It is dedicated to surface mounting, and the built-in Bluetooth antenna can greatly facilitate the rapid implementation of IoT projects.

Seeed XIAO BLE Sense is equipped with a digital microphone with pulse density modulation (PDM). It can receive real-time audio data, which allows you to use it for audio recognition. There is also a 6-axis Inertial Measurement Unit (IMU) on the board, which can be very useful in TinyML projects such as gesture recognition.

The user has a Near Field Communication (NFC) interface, a reset button and a 3-in-1 LED (user LED) with a charge LED that indicates the charging status when the battery is connected. There are 11 digital I / O that can be used as PWM pins and 6 analog I/O used as ADC pins. It supports all three popular serial interfaces such as UART, I2C and SPI.

The module can be powered by a USB type C connector (the connector is also used for programming the system) or by pins 5 V or 3.3 V. The microcontroller works with a voltage of 3.3 V, and connecting signals with a higher voltage may damage the system. The kit is Arduino compatible and can be programmed using Arduino IDEMicroPython and CircuitPython. Full documentation of the module with examples of use is available on the product page.
