I know this is probably a beginner problem but this is my first project. I am currently working on a project where data from a sensor is transmitted from one arduino to another using a mandar transceiver shield. The transmitting arduino works fine but when I plug the receiver arduino (with the exact same components and setup as the transmitter) I get an error message from my computer “Unplug the accessory using too much power”. I have checked for dodgy circuting but the setup is the same as the transmitter which works. I am using a macbook pro 2015. I have attached picture if it helps.
Thank you in advance for any help
What happens if you remove the shield from the receiver Arduino and then plug it into your computer?
