Raspberry Pi Zero Inspired ATMegaZero Arduino Compatible Board Launched for $24.90

When we reported about ATMegaZero, an Arduino Leonardo compatible board following Raspberry Pi Zero form factor last July it was not available for sale just yet.

The good news is that the Microchip ATmega32U4 board is now available on GroupGets for $24.99 plus shipping. The group buying campaign is expected to end around September 30th, and the boards will ship right after that.

The board works out of the box with the Arduino IDE for Windows, macOS, and Linux.  Last time around, I could not find any documentation, but a website has now been launched with more technical details and the resources to get started including the pinout diagram.

There are also a few options and add-ons on the GroupGets page including a 2.54mm pitch 2×20 dual male header ($2.95), and the ATMegaZero Protoboard ($4.95) that’s basically a breadboard that can be plugged on top of the board via the 40-pin GPIO header. Note if you need WiFi, you’ll need to purchase ESP-01 or ESP-01s module separately for a little over $1 shipped.
