Hi. Haven’t been able to find info on the 5V dc connector on the EVB board, in the documentation. Questions I have are -
-
Is the center pin positive?
-
What is the voltage range allowed on the 5V input?
Cheers
Herbert

Hello HEN,
you can find the schematic of the WizFI220-EVB on the product page (eucache.wiznet.co.kr/UpLoad_File … -Guide.zip). I also attached the zip-file for you. The center pin is positive.
As you can see there is a MIC5209 LDO voltage regulator embedded on the EVB. This voltage regulator can be powered with ±20 Volts, but it is not recommended to power it with more than +16 Volt. The capacitors that are used at the input pin of the voltage regulator are limited to +16 Volt and could be damaged if they suffer from a higher input voltage. I also attached the datasheet for the MIC5209.
Best regards,
Felix
