Help to recover burned DuetWifi, it is posible
-
@spirit-robotics anything between 4.5V and 5.5V will be OK.
-
@dc42 thanks
-
@alankilian ok, I will try

@alankilian ok, I will try
I connected with the mosfet, verified the voltajes, PINS, etc but dot start the board, still dead
I try with a direct USB connection, it works, the connection by pronterdace show alive the board, and the wifi connect, the screen still dnt work, I guest is insuficient ampers.
I think I can power the screen directly, maybe a need an small PSU 5V to power by the USB port the duet and directly the paneldue. Nice job... Any suggestions.
Best

Did you move the jumper from internal 5 Volts to external 5 Volts?
LINK.
Show us a photo of the LEDs.
-
@alankilian Yes, I did and check twice. I will remove the board for more test
-
If you show which LEDs are lit it will help figure out if you have proper power before moving on to other things.

@alankilian HI
This is the Duet removed from the printer on EXT Power, all pins are in place as needed
I double check the PSU and the mosfet, they are delivering voltaje, the PIN EXT is in place, but is dead. I dont know why is dead, is supposed to be ON.
In USB power is ok, is working, the LEDs 5V, 3.3V and Wifi are ON, and can connect with pronterface and by web too
I was thinking use this small PSU from a old laser cutter and connect with a USB cable to the EXT IN and another connection, maybe, for the panel due
-
It's great that the board works on USB power.
If it gets NO power when you supply external 5 Volts, I think your jumper might be bad.
Can you measuere the voltage on pins #1 and #2 on the bottom of the PCB jumper pins when you have ONLY the external 5 Volt supply connected?
-
@alankilian Good idea, I will to check the voltajes.
What should be expected with the pin EXT IN in place? without the pin in place what should be expected? -
Pin #2 will show 5 Volts with and without the jumper in place.
Pin #1 will only show 5 Volts if the jumper is in place and working. -
@alankilian thanks, I will check and return
