I am attempting to power up my Astar 32U4 LV with a 9V battery using the standard plug adapter. The battery tests at 9V, and the power runs into the terminals that are soldered to the board. Am I missing something easy? Thanks in advance
I am sorry you are having problems with your A-Star. Can you post some pictures showing all of your connections and your soldering? Can you measure the voltage at the VIN pin on the A-Star?
Sorry it’s been a long while, short notice out of town thing. I have finally got a chance to sit and have a go at it. It is working just fine now. Tough to admit, but I guess the first time around, I did not notice the actual power switch. My bad. Thanks for your time.
