OPT8241-CDK-EVM: 5V 3A power supply polarity

Part Number: OPT8241-CDK-EVM

Hi,

We are trying to evaluate this kit, and the manual specifies the EMSA050300-P5RP-SZ 5V 3A DC power supply, which is not included in the eval kit and is hard to find here (e.g. shows "discontinued" by Mouser).

It also says we can use a "equivalent" unit, so just to be sure, is the polarity of the barrel connector center-positive?

Thanks,

Steve
