Power Supply Issues - thernet Shield - 12V vs 9V vs 5V Aug 6, 2019 4:29:02 GMT Quote Select PostDeselect PostLink to PostBack to Top Post by jimmie on Aug 6, 2019 4:29:02 GMT My ShieldBuddy has an Ethernet Shield. I have been testing powering the board with different voltages. Here are my findings:1) 12V to DC Jack - Did not even try it. Please see 2) below.2) 9V to DC Jack. Works but board get too hot.3) 7.5V to DC Jack. I found this to be optimal. Supplying enough voltage and board does not get hot.My question is:Can I use a 5V (2 Amps) at Vin? I prefer this approach to powering via the DC jack with 7.5V. I cannot easily supply 7.5V to Vin due to my configuration.Thanks in advance for the community's help.
