SeeedSeeed Studio XIAO nRF52840

Overview

The Seeed Studio XIAO nRF52840 is an ultra-small development board powered by the Nordic nRF52840 SoC, featuring a 64MHz ARM Cortex-M4 with FPU. It provides integrated Bluetooth 5.0 and NFC connectivity alongside battery charge management in a compact 17.5mm x 21mm form factor. This board is designed for low-power IoT applications and tiny machine learning projects requiring a small physical footprint.

Why Choose This Part

It offers a rich set of peripherals including 11 GPIOs, 6 ADC channels, and 11 PWM channels while consuming only 5uA in deep sleep mode. The onboard chip antenna and USB Type-C interface simplify hardware integration for rapid prototyping and deployment.

Applications

Getting Started

Developers can program the board using the Arduino IDE with the Seeed nRF52 mbed-enabled boards package or through MicroPython. It features a physical reset button and internal battery pads to support quick transition from USB-powered development to battery-powered testing.

Also Consider

Arduino Nano 33 BLE Arduino - Uses the same nRF52840 SoC but provides more IO pins and a larger form factor for standard breadboard use.

Seeeduino XIAO (SAMD21) Seeed Technology - A lower-cost alternative in the same form factor for projects that do not require Bluetooth or NFC.
