Although Arduino-compatible boards are not as difficult to find in stock as a Raspberry Pi, they can still be challenging to source. The revamped Adafruit Metro Mini 328 V2 is a 5 V, 16MHz, Arduino-compatible board that fits right into the STEMMA QT and Qwiic Connect ecosystem. And is in stock.
The board still features the same ATmega328 integrated circuit, same pinout, same size, and same mounting hole locations. But, now you have the STEMMA port for prototyping without the need to solder. Just snap together and get programming. They also got rid of the old micro-USB port and upgraded to a reliable and more robust USB-C connection. It’s teeny, it’s tiny, it’s mini, and it’s Arduino-compatible! And it’s in stock! What’s not to love?
They give the board a 9/10, saying it’s “Updated and better than ever.”

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
