The Nano RP2040 Connect fits the Arduino Nano form factor.
The microcontroller for this board is the Raspberry Pi RP2040; which is a dual-core Arm Cortex M0+ running at 133MHz. It has 264KB of SRAM, and the 16MB of flash memory is off-chip to give you extra storage.
Now out of the box the originally Raspberry Pi Pico board had no wifi or bluetooth functionality without an add-on board, this was subsequently rectified by the Pico W which added wifi and also potential bluetooth support which was not enabled at release.
This board came in at £4 and £6 roughly for both versions. This also launched many other boards that used the Rp2040 microcontroller. Arduino then released the Nano RP2040 Connect which also supports Wifi and Bluetooth and has a few other bells and whistles but comes in at around £33.
It has a 6 Axis IMU sensor, a Cryptographic Co-Processor, a MEMs microphone and an RGB led. So although slightly more costly, you can see there are a few added extras on this board. The IMU for example costs around £5 and means you can use this board for a few applications out of the box such as pedometer, step detector and step counter

About
The operating voltage for Nano RP2040 Connect is 3.3V
All pins except for A6 and A7 are available for PWM.
The RGB LEDs are connected through the Wi-Fi module, so it is required to use the WiFiNINA library to use it.
