Designed for ultra-low power consumption and flexible development, it supports Arduino, MicroPython, and CircuitPython, making it ideal for next-level wearable, IoT, and TinyML applications in space-constrained environments. ## 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 ΞA 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. ## Features - POWERFUL nRF52840 MCU – Powered by the Nordic nRF52840 with a 64MHz 32-bit ARM Cortex-M4 processor and FPU, delivering capable performance for Bluetooth, wearable, IoT, and embedded development. - BLUETOOTH LE 5.4 & NFC CONNECTIVITY – Built for low-power wireless projects with Bluetooth Low Energy 5.4, Bluetooth Mesh and NFC support, plus an onboard antenna for compact connected devices, wireless sensors, and wearables. - BUILT-IN 6-AXIS IMU & PDM MICROPHONE – The Sense version adds an onboard 6-axis IMU and digital PDM microphone for motion sensing, gesture recognition, audio capture, and TinyML applications without requiring separate sensor modules. - RICH INTERFACES & FLEXIBLE DEVELOPMENT – Develop with Arduino, MicroPython, or CircuitPython and connect peripherals through UART, I2C, SPI, digital GPIO/PWM, and analog ADC interfaces, with 2MB onboard Flash for embedded projects. - ULTRA-COMPACT & LOW-POWER DESIGN – The tiny 21 × 17.5mm XIAO form factor combines low-power operation with battery charge management, making it well suited for wearables, portable sensors, and space-constrained IoT devices. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09T94SZ8K | | Best Sellers Rank | #3,543 in Computers ( See Top 100 in Computers ) #25 in Single-Board Computers | | Brand | Seeed Studio | | Built-In Media | / | | CPU Model | core_m | | Compatible Devices | Smartphones, Computers, Microcontrollers | | Connectivity Technology | I2C | | Customer Reviews | 4.1 4.1 out of 5 stars (94) | | Item Dimensions L x W x H | 21L x 21W x 21H millimeters | | Item Highlight | Bluetooth LE 5.4, 64MHz ARM Cortex-M4, Ultra-Low-Power Design for TinyML, Wearables & Battery-Powered IoT Projects | | Manufacturer | seeed studio | | Memory Storage Capacity | 2 MB | | Mfr Part Number | S9-ZIT9-5PGK | | Model Name | nRF52840 | | Number of Items | 1 | | Operating System | FreeRTOS | | Processor Brand | ARM | | Processor Count | 1 | | Processor Speed | 64 MHz | | RAM Memory Installed | 256 KB | | RAM Memory Technology | Bluetooth | | Wireless Compability | Bluetooth | ## Product Details - **Brand:** Seeed Studio - **CPU model:** core_m - **Installed RAM memory size:** 256 KB - **Memory storage capacity:** 2 MB - **Model name:** nRF52840 ## Images ![Seeed Studio XIAO nRF52840 Sense BLE Board, 6-Axis IMU & Microphone - Image 1](https://m.media-amazon.com/images/I/61xii6zcjgL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - Seeed Studio XIAO nRF52840 Sense - Supports Arduino/CircuitPython - Bluetooth5.0 NFC with Onboard Antenna, MCU with 6-axis IMU Works with Amazon Sidewalk - Raspberry Pi Zero 2W - Seeed Studio XIAO ESP32C3 - Tiny MCU Board with Wi-Fi and BLE for IoT Controlling Scenarios.
