preenfm2 and preenfm3 / Re: Bought used preenfm2, usb not working properly
« on: May 29, 2017, 08:42:38 PM »Thanks for the tips Xavier. I will try to follow your tips and let you know. I do not know what CPU board I have and also the PCB revision! How can I discover? thanks and sorry for the "newbiness"
Can you attach a picture of the whole PCB ?
The PCB revision is written on it : something like "R5d ".
For the CPU board this is the preenF405 :

And this is the CERB40 :

And don't forget to upgrade your firmware. 2.07 is the latest revision and your preenfm2 will be much more powerfull with it than it is today with the 1.06.
