## Description
The feature packed Arduino® Nano RP2040
Connect brings the new Raspberry Pi RP2040
microcontroller to the Nano form factor. Make the
most of the dual core 32-bit Arm® Cortex®-M0+
to make Internet of Things projects with Bluetooth
and WiFi connectivity thanks to the U-blox® Nina
W102 module. Dive into real-world projects with
the onboard accelerometer, gyroscope, RGB LED
and microphone. Develop robust embedded AI
solutions with minimal effort using the Arduino®
Nano RP2040 Connect!

## WiFi/Bluetooth connectivity

Wifi 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 independantly of the RP2040 through the pads under the board using SWD
