Using the Compact Mini Rboard is easy. First, connect it to your Arduino setup. You can use the relay for controlling electrical devices, and the nRF24L01 and 433M RF Receiver interfaces for remote communication. To use it as a switch in a power strip, just install it inside. When handling the board, make sure to avoid static electricity and don't expose it to extreme temperatures or moisture. For maintenance, keep it clean and check the connections regularly. If you face any technical issues, open a ticket on the Itead Support System.
