I have two Teensys 4.1 and both are powered using the same 5V source. They communicate together via RX/TX/GND.
Main Teensy has a 128x32 OLED display connected to 3.3V and two Sparksfun loadcell amplifiers also connected to the 3.3v pin.
The second Teensy(stepper motor Teensy) has a DM556T stepper driver connected to it with Steps, Dir and Ena are connected to 3.3Vpin
My machine was working very good before I added the two load cell amps, now when I run the machine, the Main Teensy reboots by itself after a while.
So my questions are:
1- Is this normal?, maybe there's a limitation on how many devices we can power on the 3.3V and that would cause a reboot?
2- Could the motor Teensy crash and make the main teensy reboot?
If it turns out to be #1, would installing a little 3.3v regulator on the main 5V source and hooking up the load cell amps fix the overload?
Thanks very much for reading this.
