Yes! We have greatly benefited from the open source community and we are dedicated to give back. The hardware is released under the Creative Commons ShareAlike 4.0 International (CC BY-SA 4.0).
Compatible Arduino’s
The Sunflower Shield is compatible with a wide range of Arduino and Arduino clones, however there are some which are not compatible. The Sunflower Shield requires 5V to be supplied from the Arduino itself, and some Arduino clones, specifically 3.3V versions such as the Arduino Pro 3.3V, feature 3.3V on the pin typically specified as being 5V. These 3.3V varieties are not compatible as 5V is required for the Sunflower Shield itself. Known compatible Arduino’s for the Sunflower Shield:
Uno, NerO, Leonardo, Mega 2560 (Others may also be compatible.)
