| Jul 23, 2018 at 21:48 | comment | added | shekit | @DrMoishePippik ok and just to confirm C2 now becomes two supercaps in series? | |
| Jul 23, 2018 at 21:23 | comment | added | DrMoishe Pippik | The diagram would look like that of @uglyoldbob, below, without C1. Drive the servos from the input side, the Pi on the output. | |
| Jul 23, 2018 at 21:09 | comment | added | shekit | @DrMoishePippik will the supercaps be in series or parellel(like the circuit below)? Also is the placement similar - CLC or CCL? | |
| Jul 23, 2018 at 20:55 | comment | added | DrMoishe Pippik | A supercapacitor packs more capacitance in a small volume. Two in series should handle 5.5 VDC. Combined with a small inductor as in the answer below should make a rock-steady supply for the Pi, with 5 V for servos drawn before the inductor.
