WebMar 12, 2024 · Remember, a ground plane in a PCB is supposed to provide a clear low reactance path for return current. The second you route a high speed digital trace over a region without any grounded copper beneath it, you’ve created a return current path that may have very large loop inductance, which could create a radiated EMI problem. WebNote that you can sometimes use a ferrite bead instead of a resistor. For I2C, as long as the series resistor is much smaller than the pullup, it shouldn't have too much effect. For I2C and SPI, you should start with 0 Ohm series resistors and only increase the value if …
