SparkFun STEMTera Breadboard | Maker Minute
SparkFun’s STEMTera is a breadboard with hardware inside to support Arduino and native USB development. With the hardware inside the breadboard, prototyping is quicker and cleaner as the MCU IOs and Arduino UNO R3 shield interface are connected directly from the PCB to the breadboard tie points. The STEMTera includes an ATmega328P for Arduino development, and an ATmega32U2 for USB communication with the host, but the ATmega32U2 can also be used for developing native USB applications. The bottom of the breadboard has a 10x14 LEGO-compatible base so the STEMTera can be directly attached to LEGO bricks.
