XIAO nRF52840 XIAO nRF52840 3PCS Pack nRF52840 (Pre-Soldered) XIAO nRF52840 Sense nRF52840 Sense 3PCS Pack 52840 Sense Pre-Soldered ## Features - 📌【Powerful CPU】As the advanced version of the board XIAO BLE, Seeed XIAO BLE Sense has equipped a powerful Nordic nRF52840 MCU which is designed in a Bluetooth 5.0 module, built around 32-bit ARM Cortex-M4 CPU with Floating-Point Unit(FPU) operating at 64Mhz. - 📌【Wireless Capabilities】XIAO BLE Sense has Bluetooth 5.0 NFC module with onboard antenna. 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. - 📌【Rich interface】Firstly, 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. It is designed in a three-in-one LED along with power LED. It supports UART, IIC, and SPI all three common serial ports. Same as Seeed XIAO RP2040, it has an onboard 2 MB flash which means it can also be programmed by Arduino, MicroPython, CircuitPython, or other program languages. - 📌【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. - 📌【Ultra-small Size】21 x 17.5mm, Seeed Xiao series classic form-factor for wearable devices.
