Dear Frank,

Please use the solution with External 1 kOhm resistor.

There is no risk of damage of the CONTROLLINO.

Hi Jarda,

thanks for your reply, but could you please explain, how this could be ?

What kind of circuit is in there that cause this voltage drop – or is it defective ?

On my other Units (MINI and MAXI Automation) I have full 5V in the /RESET Pin !

Unfortunately I don’t have another MEGA here to check that …

Dear Frank,

your CONTROLLINO is not destroyed and this is behaviour of the MEGA variant only due to the connection of more ICs to /Reset line (higher current consumption via pull-up).

With this configuration we have passed EMC imunity test, but we are going to improve it in the next production lot.

Thank you for your feedback.

Regards

Jarda
