I am using a Heltec Wifi Kit 32 to control a servo motor. All is working fine when the ESP is powered via USB and the servo attached to the 5V pin.
Now I am trying to power the ESP and Servo from an external 5V 6A PSU and not through USB.
This causes the ESP to reboot when the Servo is moving fast. I assume the voltage drops to much.
I had a look at the Heltec Wifi Kit 32 schematics, and it appears the USB 5V and 5V pin are directly connected. Any idea why the higher rated PSU can’t power both servo and ESP?
