Hello,
>1.5A @ 3.06V = 4.59W But when you say 18W, this means you calculate with 2 Motors and both windings of the motor fully powered.
>This simply is not the case in reality.
> The motors have the specifications... but you are responsible to adjust the driver to meet the motor´s...
Hello,
Although I understand the rationale around the power discussion, the problem is that it does not seem to match reality.
In another project, I have been using this cable: https://fr.aliexpress.com/item/1005004971876668.html to power an arduino nano and 2 "classic" nema17 at 1.5A@3.06V...
Hello
>Why do you need 12V if your steppers run off of 3.6?
The 0.3A/@3.6V per phase (*4) is the info needed to know the power requirement (4.32W).
However, the steppers are driven by a drv8825 which requires >=9V input voltage and which will generate the 3.6V.
I want to integrate the boost...
Hello,
I have an engineering background, but I am not a EE. Which is why I am seeking help here.
I am designing a small PCB to carry an arduino and include 2 stepper drivers (DRV8825) and one DC-DC, 5V to 12V voltage converter (<10W).
I have done the base design/pcb (visible at...
