STEMTera Breadboard has a LEGO® compatible bottom cover that enables LEGO® bricks to be connected directly into STEMTera Breadboard without using special mounting or adapters.

USB Enhancement Without Extra Components

USB Enhancement Without Extra Components

With ATmega32U2 exposed, users can now develop native USB projects with an extra 21 IO pins. These extra IO pins can work directly with the LUFA framework without having a middleman to translate messages like the original Arduino UNO.

Reduce Messy Wires

Reduce Messy Wires

STEMTera Breadboard eliminates messy wires by having two microcontrollers built inside the breadboard, thus providing direct access to ATmega328P and ATmega16U2’s IO pins.
