nRF52840 XIAO BLE Sense - XIAO BLE nRF52840 Sense - TinyML/TensorFlow Lite- IMU

Product Description

This is a 3PCs pack of XIAO nRF52840, which is powered by Nordic Semiconductor's nRF52840 chip. It supports wireless connectivity of Bluetooth Low Energy 5.4 and NFC, also is able to operate with ultra low power consumption. Featuring onboard IMU, PDM and compatibility of TensorFlow Lite and Edge Impulse, it can be your best mini Arduino-compatible dev board for embedded Machine Learning projects.

Features:

🌱 Versatile Microcontroller

Incorporate the Nordic nRF52840 chip 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

Provide ultra-low power consumption as 5 μA in deep sleep mode while supporting lithium battery charge management.

🌱 Thumb-sized Compact Design

21 x 17.5mm, adopting the classic form factor of XIAO, suitable for space limited projects like wearable devices.

🌱 Advanced onboard Functionality

Assemble additional digital microphone and 6-axis IMU in the tiny board for embedded Machine Learning applications.

Product Description:

Seeed Studio XIAO nRF52840 Sense has an ultra-low power consumption of only 5 μA in the deep sleep mode, the embedded BQ25101 chip supports battery charge management which prolongs its use time. Moreover, Seeed Studio XIAO nRF52840 Sense supports the USB Type-C interface which can supply power and download code. It also has rich On-chip Memory of 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 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 can receive audio data through the MSM261D3526H1CPM microphone. The other one is 6-axis Inertial Measurement Unit(IMU) which can be applied in TinyML projects like gesture recognition. .
