Teensy 3.0 Schematic Available

[kingforger]

MuShoo, here's a working schematic and BOM for just the teensy portion (built and it works great). The three buttons that you see that are the same are wired incorrectly. Also, VIN-PRI/VUSB-TRI and VUSB_PRIMARY is just 5V. If you were putting together your own schematic, you probably just want to connect them together to VUSB in order to power the teensy from USB or a 5V source. If you have a battery that is separate from USB, then you should hopefully be able to figure that out yourself...

In the BOM, there's a bunch of extra stuff that you won't see on the schematic. That's because it's used elsewhere in places that I should not show you. The teensy part is fine to show you all, though. No secrets there.

Otherwise, Paul did not give the bill of materials, so I just chose things that seemed appropriate (like with the ferrites, for example). It's working well, so I apparently did fine.

Thanks, Kingforger! This should be very helpful.

Old and new schematics?

The Teensy 3.0 schematic is (finally) available now.

hi Paul,

I notice the schematic in the first post and the schematic in the link differ wrt the placement of the poly fuse. In particular, in the original (Teensy 3.0) schematic posted, the poly fuse comes after VUSB pin connected to the micro USB shell connector, but in the newer (Teensy 3.0/3.1) linked schematic the poly fuse is now between the VUSB pin and the shell connector.

Obviously, this makes a difference if using a power supply capable of supplying > 500mA (say, a phone charger) and you want to draw current > 500mA for the project via the VUSB pin.

Just seeking to clarify that I am indeed reading this all correctly.

Cheers,

-Mark

The old schematic on this thread has an error. The one on the website was updated some time ago.

I've edited the original post on this thread, with a notice about the error.

OK, so both the Teensy 3.0 and 3.1 have always had the 500mA poly fuse between the USB shell connector the VUSB pin?
