FEZ Utility for the Raspberry Pi

The Raspberry Pi is an amazing little piece of hardware. Essentially, a $35 PC. However, when it comes to the Internet of Things and connecting sensors and control modules, it falls a little short. Its male pins are not easy to wire, the pins are not 5V tolerant, there are no PWM outputs and there are no Analog inputs. This is true for both the original Raspberry Pi and Raspberry Pi 2.

Thanks to the all new FEZ Utility, connecting all kinds of sensors and devices couldn’t be easier!

Key Features:
[ol]All Raspberry Pi’s original pins are exposed (and labeled) on female headers.
13 5V-tolerant GPIO pins.
14 PWM outputs.
8 Analog Inputs.
4 LEDs, 2 of them are PWM ready for dimming.[/ol]
The FEZ Utility is compatible with Raspberry PI 2 model B and Raspberry PI 1 model B+. Complete drivers are provided for Windows 10 but Linux can work as well.

If you are planning on connecting anything to your Raspberry Pi besides a USB cable then you must own the very versatile FEZ Utility HAT.

@ Gary - Very nice and … :wall:

I tried to warn you to wait on your order but the FEZ Cream sent you over the edge.

Truth, truth … but it was a perfect timing otherwise my wife would never let me order this magnitude of things (she was on a vacation with the kids and I was left home alone to get work done, now she knows it should never happen again … :snooty: )

Tempting, but I’m already sitting on the Hat and Cream just working on ideas for them.

BTW, combining GHI screws, nuts, and standoffs makes for perfect spacers!

GHI may wish to carry the Raspberry PI2 just to allow on one-stop shopping.


Agreed. Now, if only the RPi fit the holey board in both dimensions …

@ Gary -

If I have a FEZ Hat why should I get a FEZ Utility.

Just asking why is there both?

@ willgeorge -

To me the Hat is more about being able to tinker in a self contained package, so you get buttons, lights, sensors, controllers, etc.

The Cream is something for someone who just wants a nice easy way to connect their existing stuff to the Pi without all the work of handling voltage checks and basic interfacing.

Where does the “Fez Utility” fit in with your paradigm, Squeebee? Who would choose that over the “Fez Hat” or “Fez Cream” ?

I’m surprised utility is bigger than the hat… that hat has way more stuff it seems.

@ mtylerjr - bigger hat? All hats are the same size.

@ mtylerjr - Typo, I meant the utility. The Cream is for connecting Gadgeteer, obviously. Essentially the Cream and the Utility are the same concept, but Cream for Gadgeteer modules and Utility for generic ones.

FEZ HAT has motor and servo drivers, for one. Yes, you can drive servos with PWM, but having the terminals exposed is a nice convenience. Add in the sensors, and you have a nice all-in-one board for building robots without adding a bunch of stuff. Plop a Pi with FEZ HAT onto a chassis, and go to town.

I see FEZ Utility as being more about making it easier to get to the I/O ports on the Pi, as well as having access to stuff the Pi doesn’t offer natively. The fact that all the pins are actually LABELED will be enough to ensure it’s popularity. :slight_smile:

Can I please see a shot of the Utility mounted to a Pi ? How am I expecting to get access to pins ?

If I understand correctly, the I/O pins are passthrough to one of the pin blocks on the top. So you wouldn’t be able to add another HAT, but you can get to all the pins.

Does that help?

@ devhammer - correct.

@ Gus - the fez hat is 45mmx36mm
The fez utility is 65mmx56mm

At least according to the specs ghi lists on their respective pages

That’s why I said I was surprised the fez utility was bigger than the fez hat

Are you saying there’s a header on the bottom of the board (that none of the images show so far) ? If so then it makes more sense but a picture of it mounted would alleviate all concerns.

@ mtylerjr the additional header block is the bit that takes extra space, so I can understand why it’s a different size.

@ Brett - no, the first female header is simply a map of the original rpi pins, but now female instead of male… And labeled right there for you.

Still not helping >:) A picture of it mounted would help… assuming it should be mounted on Pi?
