I have connected a 9 volt battery to the barrel connector on my relay shield and everything is fine for ~45 seconds then the power light on the shield goes out and the rgb led on the core dims greatly and has the red and green lit up. pressing the reset button and unplugging and re-plugging the barrel connector both result in the boot sequence and once it is about to reach breathing cyan it returns to the dim red and green. This has occurred when using tinker to control the relay as well as my own code.
I’m not sure if I’m doing something wrong.
Thanks in advance for any insight that you can offer
