I am trying to drive a servo with some medium load, but nothing considerable. This reset happens even when attempting to move the servo fast without a load.
I am guessing I am having some EMI or noise issues. I tried using a more powerful power supply, and issue persists. When the servo moves fast or under load, the Photon turns the LED red and then reboots.
This is how the power is hooked up:
— 5VDC —> |SERVO POWER|----> REGULATOR ----> |PHOTON|
The Servo is being powered before the regulator but after the 5V DC wall power supply.
The Servo ground goes to the common ground plane in my custom PCB.
I am attaching the schematics of my board:
The servo is hooked to the 5VUNR net.
This are the headers I use to connect to the servo.
Any help would be greatly appreciated.
This only happens with a Futaba S9350 High Speed, High Torque Servo. If I use a standard servo when I try to stall it it allows me to stall it without resetting the Photon.
