#166365 - Ground plane? Responding to: Aleksandar Stancic's previous message |
Aleksandar, do you have a solid ground plane? If not, then even the most superb reset controller might be a waste to time. I have seen that you run a 48MHz oscillator on your board. That's a good moment to switch to a 4layer-board design, even if it costs much.
Good luck, Kai |
