Whether you’re a beginner stepping into the world of IoT or an advanced user looking to incorporate it into your next product, the Nano RP2040 Connect is a versatile choice.

Key features of the Nano RP2040 Connect:

Tiny footprint: Designed with the well-known Nano form factor in mind, this board’s compact size makes it perfect for embedding in standalone projects.
Wi-Fi and Bluetooth: The u-blox NINA-W102 module provides Wi-Fi 802.11b/g/n and Bluetooth 4.2 connectivity, making it ideal for IoT applications.
Onboard sensors: Features an LSM6DSOX 6-axis IMU (accelerometer and gyroscope) and an MP34DT06J digital microphone for audio and motion sensing applications.
Security: Includes an ATECC608A cryptographic coprocessor for secure IoT applications.
RGB LED: An onboard RGB LED driven by the NINA module for visual feedback.

Connections and IOs

The Arduino Store [1] and Arduino Docs [2] have detailed information about board connections. Download the datasheet [3] for more detail.

Flashing

Using UF2

The easiest way to flash the board is using the UF2 bootloader. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b arduino_nano_connect samples/hello_world
west flash

Serial Console

Connect to the serial console using the USB port:

$ minicom -D /dev/ttyACM0

You should see the following message:

Hello World! arduino_nano_connect

Debugging

You can debug an application using OpenOCD and a debug probe. Here is an example for the Hello World application.

# From the root of the zephyr repository
west build -b arduino_nano_connect samples/hello_world
west debug
