Processor

• The processor is based upon the new Raspberry Pi RP2040 silicon (U1). This microcontroller provides opportunities for low-power Internet of Things (IoT) development and embedded machine learning. Two symmetric Arm® Cortex®-M0+ clocked at 133MHz provide computation power for embedded machine learning and parallel processing with low power consumption. Six independent banks of 264 KB SRAM and 2MB are provided. Direct memory access provides fast interconnect between the processors and the memory that can be made inactive along with the core to enter a sleep state. Serial wire debug (SWD) is available from boot via the pads under the board. The RP2040 runs at 3.3V and has an internal voltage regulator providing 1.1V.
• The RP2040 controls the peripherals and digital pins, as well as analog pins (A0-A3). The I2C connections on pins A4 (SDA) and A5 (SCL) are used for connecting to the onboard peripherals and are pulled up with a 4.7 kΩ resistor. SWD Clock line (SWCLK) and reset are also pulled up with a 4.7 kΩ resistor. An external MEMS oscillator (U7) running at 12MHz provides the clock pulse. Programmable IO helps to the implementation of arbitrary communication protocol with minimal burden on the main processing cores. A USB 1.1 device interface is implemented on the RP2040 for uploading code.

Wi-Fi/Bluetooth® Connectivity
Wi-Fi and Bluetooth® connectivity is provided by the Nina W102 (U2) module. The RP2040 only has 4 analog pins, and the Nina is used to extend that to the full eight as is standard in the Arduino Nano form factor with another 4 12-bit analog inputs (A4-A7). Additionally, the common anode RGB LED is also controlled by the Nina W-102 module such that the LED is off when the digital state is HIGH and on when the digital state is LOW. The internal PCB antenna in the module eliminates the need for an external antenna. The Nina W102 module also includes a dual core Xtensa LX6 CPU that can also be programmed independently of the RP2040 through the pads under the board using SWD.

6-Axis IMU
It is possible to obtain 3D gyroscope and 3D accelerometer data from the LSM6DSOX 6-axis IMU (U9). In addition to providing such data, it is also possible to do machine learning on the IMU for gesture detection.

External Memory
The RP2040 (U1) has access to an additional 16 MB of flash memory via a QSPI interface. The execute-in-place (XIP) feature of the RP2040 allows external flash memory to be addressed and accessed by the system as though it were internal memory, without first copying the code to internal memory.

Cryptography
The ATECC608A Cryptographic IC (U4) provides secure boot capabilities alongside SHA and AES-128 encryption/decryption support for security in Smart Home and Industrial IoT (IIoT) applications. Additionally, a random number generator is also available for use by the RP2040.

Microphone
The MP34DT06J microphone is connected via a PDM interface to the RP2040. The digital MEMS microphone is omnidirectional and operate via a capacitive sensing element with a high (64 dB) signal to noise ratio. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process dedicated to produce audio sensors.

RGB LED

The RGB LED (DL3) is a common anode LED that is connected to the Nina W102 module. The LED are off when the digital state is HIGH and on when the digital state is LOW.

Power Tree

The Arduino Nano RP2040 Connect can be powered by either the Micro USB port (J1) or alternatively via VIN on JP2. An onboard buck converter provides 3V3 to the RP2040 microcontroller and all other peripherals. Additionally, the RP2040 also has an internal 1V8 regulator.

Board Operation

Getting Started – IDE
If you want to program your Arduino® Nano RP2040 Connect while offline you need to install the Arduino® Desktop IDE [1] To connect the Arduino® Edge control to your computer, you’ll need a micro USB cable. This also provides power to the board, as indicated by the LED.

Getting Started – Arduino Web Editor
All Arduino® boards, including this one, work out-of-the-box on the Arduino® Web Editor [2], by just installing a simple plugin.
The Arduino® Web Editor is hosted online, therefore it will always be up-to- date with the latest features and support for all boards. Follow [3] to start coding on the browser and upload your sketches onto your board.

Getting Started – Arduino Cloud
All Arduino® IoT enabled products are supported on Arduino® IoT Cloud which allows you to Log, graph and analyze sensor data, trigger events, and automate your home or business.

Sample Sketches
Sample sketches for the Arduino® Nano RP2040 Connect can be found either in the “Examples” menu in the Arduino® IDE or in the “Documentation” section of the Arduino website [4]

Online Resources
Now that you have gone through the basics of what you can do with the board you can explore the endless possibilities it provides by checking exciting projects on ProjectHub [5], the Arduino® Library Reference [6] and the online store [7] where you will be able to complement your board with sensors, actuators and more.

Board Recovery
All Arduino boards have a built-in bootloader which allows flashing the board via USB. In case a sketch locks up the processor and the board is not reachable anymore via USB it is possible to enter bootloader mode by doubletapping the reset button right after power up.
