Re: Power Switch
If you place a capacitor in parallel with your inputs, you can use a switch that breaks and then joins on the other side, and the capacitor can carry you through the transition without resetting the linux board. The more current that the circuit draws, the longer the transition time, and the more sensitive the circuit (in terms of the maximum acceptable voltage drop), the larger the capacitor you will need. Assuming that the allowable voltage drop is small compared to the nominal voltage, The necessary capacitance is simply
C = t * I / ΔV, where t is the switching time, I is the current draw, and ΔV is the acceptable voltage drop.
