I made a PCB to control 6 servos (MK 996) on a robotic arm. The board also supplies two LCD/touch modules. The device is controlled by a Teensy 3.2. When I drive a couple servos the LCD panels blip. I believe that I need to add some capacitors to either or both servo bank and LCD panel bank. The power is 5V and I am supplying 5A. What size of capacitor(s) should I use and where?
