I'm planning on using a Teensy 3.2 to drive a Nema 17 stepper (2 amps/1.2 amps per leg) along with several limit switches and LEDs as well as a bluetooth module.
I'll be using a Lipo 3S battery (11.1v) to drive the stepper. The bluetooth module needs 3.6 to 6v but I've seen several forum threads which say 3.3v works. I also have an LM2596 voltage converter that can up or down convert.
Several of the schematics for the DRV8825 stepper driver use a 100 uF electrolytic capacitor.
I have several questions about the wiring:
1. Can the Teensy and the DRV8825 run from the 11.1v battery and drive all of the modules properly?
2. Should I use a larger capacitor or multiple capacitors when driving everything from one battery?
3. Should the On/Off switch go before or after the capacitor?
4. I'll also be uploading programs with the USB. Will there be a problem having the battery connected during the uploads?
