Power Supply for Bipolar Stepper Motors

[randomuser1219]

Hello. So I need to order a power supply for my project, the issue I'm running into is amps. So I am using a breadboard (1 amp rating), two bipolar Nema 23's (3V 2.3A), and 2 TB6612FNG. My original plan was to just hook a power supply to the breadboard, but this seems less and less like it will work and more like a melted breadboard.

Giving stepper motor location capabilities

I am aware that for my particular issue a servo motor would solve all of my problems, however it is not within the given budget as the project would require 2-3 servo motors. I need to operate an arm that has a 90 degree range and a base that has a 360 degree range. The issue I am encountering is that I need to be able to set these to specific locations based off of a reference point. I am decently sure that I can do it with an unnecessarily difficult code. This would work but I do have a fear …

Bipolar Stepper Motor w/ Darlington Array

A big lesson in the ordering of parts was learned, but the result is that I have ended up with three bipolar stepper motors and a lot of ULN2003A and no power supply. My understanding is that I will need to switch the Darlington array with an H-Bridge. I'd like to double check first before going through the reordering process. I don't have much experience with darlington arrays so I'd greatly appreciate any advice. [Mod edit Please note that @randomuser1219 has 3 questions open on related but …

it makes no sense to route high currents through a breadboard.

Anyway you cant connect a surface mount TB6612FNG to a breadboard - so I'm guessing you are using a module?

I'd suggest you invest in some headers and prototyping board and build your circuit on that.

SparkFun Motor Driver - Dual TB6612FNG (with Headers)

[randomuser1219]

I'm on a project with pretty limited budget, and we had 6 breadboards. My guidance was "Ah, you have 6 so if three melt, you'll be fine". I'll see if I can find a prototyping board hanging about, I am using a TB6612FNG with headers. Luckily right now I'm working on just testing baseline code and motor function, so amperage and voltage hasn't been a huge concern, but it will become a problem as the project comes together. Thank you for your advice.

If you take some 14ga solid copper wore you can bend it to follow the holes and it carries way more current
