Open up new IoT possibilities with Seeed XIAO BLE for TinyML and Seeed Fusion PCBA service

Seeed Studio has just released the highly anticipated addition to the XIAO series, Seeed XIAO BLE – nRF52840, a powerful Bluetooth LE microcontroller supporting multiple protocols including Bluetooth 5.0, NFC and Zigbee.

What’s so special about it?  Seeed XIAO BLE and the advanced version, Seeed XIAO BLE Sense are designed for wearable devices and Internet of Things projects, taking advantage of the Nordic nRF52840 MCU’s Bluetooth capabilities of working at long distances, at low power yet with high performance.

The onboard antenna, small size and surface-mountable design make it highly suitable for connected, wearable designs, Internet of Things projects and the possibilities to run AI using TinyML and TensorFlow™ Lite.

Get inspired! To better support Internet of Things developers and enthusiasts to utilize this tiny yet feature-rich board, and accelerate the implementation of IoT industry, smart wear projects and TinyML, Seeed has launched a sponsorship event, manufacture your Seeed XIAO BLE prototype for free with Seeed Fusion PCBA service.

What is Seeed XIAO BLE?

Seeed XIAO BLE – nRF52840 is a low-power, ultra-small size, super cost-effective Bluetooth development board based on the powerful Bluetooth 5.0 MCU — Nordic nRF52840.

What are the key features of Seeed XIAO BLE?

One look at Seeed XIAO BLE and it’s hard to imagine that this cute board is a powerful wireless development board. Sharing the same form-factor with another Seeed favorite, Seeed XIAO BLE uses the thumb-size, surface-mountable design as other boards in the XIAO family. But on this tiny board is the powerful Bluetooth ARM Cortex®-M4 MCU, Nordic nRF52840 with Bluetooth 5.0 BLE, NFC and Zigbee support, an onboard antenna, battery management chip and 2MB high-speed QSPI flash for MicroPython and CircuitPython programming.

In addition to its small size and battery management, the ultra-low power consumption with a deep sleep current of less than 5μA makes it ideal for battery-powered IoT applications, wearables and small projects. And with the onboard QSPI flash, Seeed XIAO BLE is fully compatible with Arduino IDE & MicroPython/CircuitPython programming languages, and the large comprehensive libraries make it easy to get started with IoT projects.

With new wireless capabilities and as the smallest and most versatile nRF52840 development board available, Seeed XIAO BLE is set to be a gamechanger in the IoT and wearables space.
