Yup, that’s what I expected to see in my mind’s eye. You may not need to LCD display to run things entirely by remote control.
Before trying it again, I would definitely see if your wallwart is delivering 5.0 volts (or hopefully NOT more ) before it destroys more boards. Don’t hook it up to your new board before you check it out.
Assuming it’s running at 5.0v out, I would check the key supply lines on the board with an VOM to make sure everything is stable. If fed correctly, your voltage regulator chip should not be overheating (Obvious).
Fortunately, there are not that many chips on the DreamCatcher that on may be able to trouble-shoot it down to the component level. As long as you uP is running, you can fix most of that on your bench.
