Seeed Studio XIAO nRF52840 (XIAO BLE)
Seeed Studio XIAO nRF52840 (XIAO BLE) is a Bluetooth-enabled development board built around the Nordic nRF52840 chip, packed into the classic 21 x 17.8mm XIAO form factor. It runs an ARM Cortex-M4 with FPU at up to 64 MHz and is supported by Arduino, CircuitPython, and MicroPython, making it a solid choice for both wireless prototyping and low-power embedded projects.
Wireless Connectivity and Low Power Design
The board includes Bluetooth Low Energy 5.4 with an onboard antenna, along with NFC connectivity, all in a single compact module. Power design is equally considered, with deep sleep consumption as low as 5 μA and built-in lithium battery charge management, making it well suited to battery-powered and wearable applications.
Thumb-Sized and Production-Ready
At 21 x 17.8mm, it keeps the classic XIAO footprint, and its breadboard-friendly SMD design with no components on the back makes it easy to work with on the bench or integrate into a finished product.
