Frequently Asked Questions
Do I need this shield to use Grove modules? No — you can wire Grove modules manually. But the shield makes it plug-and-play with no jumper wires.
Does it work with ESP32 or Raspberry Pi? This shield is designed for the Arduino UNO form factor. For other boards, look for dedicated Grove hats/shields for your platform.
