Thanks guys!
Yeah, it wasn't too difficult, but an important step is planning. You need to lay everything out on the board, make sure it will fit, and visualize the wiring. If you don't think you can wire through a small gap, or are afraid you'd accidentally bridge some connections, try rearranging until you get a manageable structure.
I made a few mistakes in my design:
- The chip is between components, so it's very difficult to remove
- I forgot to connect the external power's ground, so that won't work until I do
- I need to clean off the excess flux. I read somewhere that it's a little conductive, like water, and can short things out. I've discovered that even with the jumper removed, the power LED is still glowing dimly, telling me that this is true.
