I am new to pololu forum and to electronic world also, so please excuse me if this question is too easy, but I looked for a long time and I don’t know what to do.
My problem is the next one :
I bought a Nema 17 stepper motor (this one : https://www.pololu.com/product/2267 ) and it’s driver (this one : https://www.pololu.com/product/2967), and I want to make them work with a nrf51822 BLE device, actually I can make it work with the nrf51dk from nordic semi conductors when I plug it in USB on my laptop but I would like to make it work with AAA batteries, that delivers 1.8A of current and 6V (I have 4 of them).
The problem is that the nrf51822 BLE device accepts 3.6V as maximum voltage, and the Nema17 2.6V, and I don’t want to break them both with a too high voltage, so I tried to reduce it with a voltage divider but it reduce the current to 0A, so nothing work after.
So I need to reduce the voltage to make everything safe but I also need to keep the current at it’s maximum level.
I was thinking to use a voltage regulator like this one : https://www.newark.com/rohm/ba33dd0t/fixed-ldo-voltage-regulator-3v/dp/08X1226
But I Wonder if the output current of 2A is not too high for my stepper motor.
I really hope that someone can help me,
Thank you very much!
