Arduino has shrunk the UNO R4 with the Arduino Nano R4 board equipped with the same 48 MHz Renesas RA4M1 32-bit Arm ...

The Nano ESP32 supports both Micropython and Arduino programming languages, providing a clear path for those already familiar with one platform to easily switch back and forth as needed.

Like the Nano, the Micro's size and male pin headers make it perfect for prototyping with a breadboard. However, Arduino also offers this board without headers pre-soldered.

Other features of the Maker Nano RP2040 small board which measures just 49.53mm x 21.08mm in size include support for the Arduino IDE, CircuitPython and MicroPython.

Four new Nano boards join Arduino's lineup.SEE: How to build a successful developer career (free PDF) The cheapest and simplest of the new lineup is the Nano Every, which costs $9.90 and is based ...

The Nano Every is a pin-equivalent substitute, so previous code and wiring will still work. Arduino has also swapped out the Nano's mini-USB connector in favor of micro-USB.
