# Can I use a breadboard to power multiple SG90 servos?

I am planning on using 10 Towerpro SG90 servos, which operate at 4.8V or 6V and can require a maximum stall current of 700ma. If I use a breadboard like this one (https://www.amazon.com/gp/product/B073ZC68QG/), will I be able to supply 5v @700ma to all 10 servos? I am confused because one of the customers asked "What is the maximum current rating on the power supply module?" and the answer was "The Power Supply Module Maximum Output Current: < 700ma." Does that mean each servo that is connected to the breadboard gets 700ma max or does it mean that the current all the servos draw combined is under 700ma?

• yes to does it mean that the current all the servos draw combined is under 700ma? – jsotola Jul 20 at 0:24
• the breadboard is ok for quickly testing one or two servos ... it is not suitable for use in a final project ... the wires are clamped loosely in the breadboard, which makes the wire connections susceptible to failure and possibly overheating – jsotola Jul 20 at 0:28
• @jsotola What would I use in a final project with 10-20 servos in order to distribute the power from a battery? Could you provide any links or model names so I can look into purchasing them? Thanks! – nothing Jul 20 at 3:54
• try using a perfboard or a veroboard and three rows of pin headers ... here is an example ... instructables.com/id/ESP32-Robot-Using-Servos ... add heavy wire to two of the pin rows .... or this diyodemag.com/projects/servo_power – jsotola Jul 20 at 5:12
• @jsotola Thanks for the links! However, both websites only use 4-5 servos and involve soldering. Is there any way to power 10-20 servos from one/two battery sources without soldering? Also, by thick wire, do you mean like a 14 AWG wire (will my robot be drawing 700ma x 20 [14A] at max?)? What would I use to connect the battery to the servos (meaning - what type of board / device would I connect the battery to, which would regulate the voltage to 5v, and then I could connect 10-20 servos to)? Sorry for all the questions; I am new to this. Thanks! – nothing Jul 20 at 6:03
