## Overview

The Seeed Studio XIAO nRF52840 Sense is a compact, ultra-powerful microcontroller board featuring a 64MHz ARM Cortex-M4 CPU with FPU, Bluetooth 5.0 and NFC wireless connectivity, and onboard sensors including a 6-axis IMU and digital microphone. Designed for wearable and IoT projects, it supports multiple programming languages and offers versatile interfaces, making it a top choice for developers pushing the boundaries of TinyML and smart device innovation.

## Description

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. 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. In 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. Same as XIAO BLE, 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. 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.

Review: Works no problem, I got it because of the embedded IMU and everything worked like a charm with Arduino IDE - BLE included. Pleasure to work with!

*by C***D on 17 September 2025*

Only two of the three came. I could see the hole in the box for the third, but for some reason, only two were in the packet! Other than that, This board is fantastic for ultra-low power projects. Be aware that this board does not contain Wi-Fi and is Bluetooth only, and so for projects that require Internet access, go with something like the ESP 32 instead.
