+The pyboard is a compact and powerful electronics development board that runs MicroPython. It connects to your PC over USB, giving you a USB flash drive to save your Python scripts, and a serial Python prompt (a REPL) for instant programming. Requires a micro USB cable, and will work with Windows, Mac and Linux.
+
+There are 3 main ways to control the pyboard:
+
+*   **REPL:** Connecting to your PC via USB, the board appears as a USB virtual comms port (CDC VCP) and you can use any serial program to connect and get a Python REPL prompt. This allows you to instantly type and execute Python commands, just like you would when running Python on your PC. You can also redirect the REPL to any of the UARTs on the pyboard.
+*   **Remote script:** You can change from REPL to raw REPL mode by sending ctrl-A, and then in raw REPL mode you can send an arbitrary Python script to the board for it to execute immediately. A Python script is available which makes using this mode very simple: you just run python pyboard.py script_to_run.py and this will execute script_to_run.py on the pyboard, returning any output.
+*   **From file:** The pyboard has a small, built-in filesystem which lives in part of the flash memory of the microcontroller. It also has an SD card slot if you want to extend the available storage. When you connect the pyboard to your PC, it appears as a USB flash storage device and you can access (mount) the internal filesystem and the SD card this way. If you copy a Python script to the filesystem and call it main.py then the board will execute this script when it starts up. This way you can run scripts without being connected to a PC.
+
+**Main features of the hardware:**
+*   STM32F405RG microcontroller

+
+Meet the only connected RP2040 board. It fits the Arduino Nano form factor, making it a small board with BIG features.
+
+The brain of the board is the Raspberry Pi RP2040 silicon; 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.
+
+But what’s really exciting is the on-board connectivity options. The hugely popular and highly adaptable u-blox NINA-W102 radio module is on there to make this a true IoT champion. This also means you can harness the power of the cloud, with fully Arduino Cloud compatibility.
+
+It’s got on-board, built-in sensors to turn your builds into powerhouse projects, too. Microphone and motion sensing add a depth of possibilities that’s almost impossible to find in a board of this size.
+
+The Arduino Nano RP2040 Connect is the premium choice for RP2040 devices, and the perfect option for upgrading your projects and unlocking the potential of new ones.
