Product description
Seeed Studio XIAO nRF52840 is a compact development board based on Nordic Semiconductor's nRF52840 microcontroller with a 32-bit ARM Cortex-M4 processor running at 64 MHz and integrated Bluetooth Low Energy. The board is designed for developing wireless IoT devices, wearable electronics, and battery-powered applications.
The board features a built-in Bluetooth antenna, 2 MB of additional flash memory, and support for UART, I²C, SPI, and NFC communication. It also includes an integrated lithium battery charging circuit, USB-C connector, reset button, and status LEDs. Its compact design, with components mounted on only one side, makes it suitable for surface mounting onto custom PCBs.
The XIAO nRF52840 can be programmed using Arduino IDE, MicroPython, and CircuitPython.
