Adafruit Motor Shield v2.3

by Sdot88 on Wed Jul 17, 2019 11:17 am

Adafruit Motor/Stepper/Servo Shield for Arduino v2 Kit - v2.3
PRODUCT ID: 1438
https://www.adafruit.com/product/1438

The product page says that this shield can control 2 stepper motors. Can the stepper motors be controlled (move) independently or will they both move at the same time?

Thanks.

One question I have: when the docs say the MOSFET drivers have 1.2A per channel current capability, this means that the shield can (at most) drive two stepper motors both with 1.2A per phase, correct? Or is it 1.2A overall, so each motor must be 0.6A or less per phase?

The shield has 2 dual H-bridges. Each H-bridge can handle up to 1.2A continuous. Since most stepping modes have 2 phases energized at a time, that is 2.4A per motor or 4.8A total.

See this guide for details of stepper operation:

I plan on using a 5 wire stepper motor and a 4 wire stepper motor with this shield (on an Uno). With this setup, what pins would be used on the Arduino? (Aside from A4 and A5 by the shield.)

Would these pins be un-usable by other modules, such as an NRF24L01 (which requires pins 11, 12, 13, and I believe 2 other digital pins)? If so, is there a configuration/setup that would make it possible?

Thanks

P.S. I'm new to all this, so please correct anything I got wrong.

A4(SDA), A5(SCL) +5v, GND.

All pins remain usable. SDA and SCL are committed to the i2c bus and cannot be used in analog input mode. Other i2c devices can be connected to SDA and SCL - provided there are no address conflicts with the shield.
