Seeeduino New Power Connector


  1. Can anyone clarify what the size/polarity of the new DC Power Jack is ? 2.1mm or 2.5mm

i.e. Is it fully Arduino UNO compatible ? +ve centre pin

  1. Can you use USB to power the Seeeduino v3.0 only if 5v mode is selected ?

Please can this detail be added to Seeduino v3.0 spec page.

Sorry, I’m an engineer and this stuff matters.

Hi there,

1.Yes it is compatible with Uno.

2.Yes you can use 5V by USB cable to supply power to seeeduino.
