RST LED

Post by JOEG » Wed Jan 29, 2020 12:31 pm

Hello,
I've been working with a MEGA for a while, but now the RST LED is constantly on and I can't upload any new sketches to my device.
I would appreciate any assistance you could offer.

Hello,
please try to check the reset button mechanically. If you open the housing, it can be, that the reset button is pressed all the time.

Regards

Hello,
I Opened the housing and checked the resistance between the separate terminals of the button.
The maximal resistance is ~50 ohm. Isn't this too low?
I opened the button and removed the cap that connects the terminals when pushed, bit I still read a very low resistance across terminals.
The even lower resistance for the open channel is ~0.5 ohm, which makes sense.
