Seeed Studio XIAO nRF52840 Sense is carrying Bluetooth 5.0 wireless capability and is able to operate with low power consumption. Featuring onboard IMU and PDM, it can be your best tool for embedded Machine Learning projects.
Seeed Studio XIAO nRF52840 Sense is carryingBluetooth 5.0wireless capability and is able to operate withlow power consumption. Featuring onboard IMU and PDM, it can be your best tool for embedded Machine Learning projects.
Seeed Studio XIAO Series are diminutive development boards, sharing a similar hardware structure, where the size is literally thumb-sized. The code name "XIAO" here represents its half feature "Tiny", and the other half will be "Puissant".
Features
Versatile Microcontroller:Incorporate theNordic nRF52840chip with FPU, operating up to 64 MHz, mounted multiple development ports, supported by Arduino / CircuitPython
Wireless Capabilities:Implement Bluetooth 5.0, BLE functions with onboard antenna, also provide NFC connectivity
Elaborate Power Design: Provideultra-low power consumptionas 5 μA in deep sleep mode while supporting lithiumbattery charge management
Advanced onboard Functionality:Assemble additionaldigital microphoneand6-axis IMUin the tiny board for embedded Machine Learning applications
Thumb-sized Design:21 x 17.5mm, Seeed Studio XIAO series classic form-factor, suitable for wearable devices
Seeed Studio XIAO nRF52840 Sense has anultra-low power consumptionof only 5 μA in the deep sleep mode, the embedded BQ25101 chip supports battery charge management whichprolongs its use time. Moreover, Seeed Studio XIAO nRF52840 Sense supports the USB Type-C interface which can supply power and download code. It also hasrich On-chip Memoryof 1 MB flash and 256 kB RAM, and an Onboard Memory of 2 MB QSPI flash. 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. 1 Reset button, 1 3-in-one LED, 1 Charge LED, and 1 Bluetooth antenna are on board, allowing developers to debug their code very easily.
As the advanced yet smaller version of the Seeed Studio XIAO nRF52840, it carriestwo extra onboard sensors. One of them is adigital microphonecreated 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 can receive audio data through the MSM261D3526H1CPM microphone. The other one is6-axis Inertial Measurement Unit(IMU)which can be applied in TinyML projects like gesture recognition.
The powerful performance makes itperfect for TinyML AIoT projects requiring gesture/voice recognition, and the tiny size allows it to be used in wearable devices and Internet of Things projects, not just for prototypes but the mass production. Furthermore, Seeed Studio XIAO nRF52840 Sense is friendly to the communities for itsstrong software compatibilities, which supports Arduino, Micropython, and CircuitPython. Except for the software, flexible I/O allows it to speak to almost any external device.

Unable to install the card because there was no screw included. The wifi antennas aren't great quality but they'll do the job. Overall, decent service but upset about the lack of screw inside. Thanks.
The item was packed well and securely. The delivery was quick too. But not sure why, they did not include a screw for installing the wifi card. Not sure why.
