Placa Principal Hércules impulse 500

Hello,

Welcome to the users forum.

1) I am not sure of what you call "la placa principal", but if you mean the printed circuit board, you should contact Hercules support team on
https://support.hercules.com/en/contact-en/

2) Please update your profile and to use in your name only letters of the latin alphabet since your using a letter from another origin causes a display bug in your name on the forum so that the maintenance bot of the forum may block your profile in believing it is a fake profile.
