 Where is the great search brought to you by did you keynote fruit? Thanks. Did you key? This is the time of the week where ladies use the power of engineering to help you Yes, you find the chips parts and more that you need lady Eda. What are you looking for this week? I'm glad you asked this week I've been doing a redesign of a TFT feather wing and The TFT feather has an interesting navigation switch on it and I realized This is a pretty cool weird part that I would like to show because the original manufacturer Like stopped making it, but there's an alternative. That's basically pink compatible. So let's go to the overhead and I'll show it off. Okay, so One thing that's uh, you know, if you're if you're adding buttons in a user interface to Project, you know, it's very common to have like a navigation thing like up down left right And then usually a select so you can go through a menu or you can Change specifications, this is a little joy stick as well. That's another option and this is this this one doesn't have a select It's only a Two-axis joystick, but usually, you know, you'll have this and then maybe I'll have a select button next to it We don't also have a joystick. We recently put into the shop that is through hole But does have a select on it Get some good focus here This nav switch is one that I like quite a bit so these nav switches they're a little bit more compact than a Joystick and they're not this is, you know, true analog joysticks. We need two ADC's X and Y and you can measure, you know in the center. It's you know ADC VDD divided by two and then as you go left and right it goes from zero to VDD the these Navigation switches they yeah, they tilt so you can kind of see that they tilt Left right up and down and they do have a select and they're kind of clicky because they really are Five mechanical switches. So I call them five-way navigation switches, although Some would say it's two axes plus select different ways of talking about it But I like them because they're not that much bigger than like two tactile switches and they're definitely smaller than four tactile switches and they're very Logical you're like, oh, it's a little joystick like I understand what you want me to do You're you know, you want me to move up down left right? And so In case people wanted to add these to their products, I thought I'd show This part and some other parts on ditch key. There's a couple navigation switches. Okay, so this is the Just show this is this was the design and this is the the footprint. So it's nice is that it has five switches and then they have one common and five pin connections so they looks like This you know one common up up down left right and then select in so you just need four GPIO pens and You connect the common to either ground or power whichever one you want and you just need pull-ups so And then here is just in case You want to see a nice big picture? Oh, here it is so this is the That what it looks like in in big big letters So these are called navigation switches and so watch out because there's also thumb Sticks, right and that's that's kind of similar and sometimes they are grouped together, but thumbsticks tend to be Just small joysticks that are analog So you see these these a pimp switches. I mean these are very fancy You know, we have this one like I said, this is XY so but not Select in some of these have selects some of them don't but thumb switches tend to be tend to be tend to be and long to access So instead what we want is I'll go to the entire cabinet gory Navigation switches now what I'll see is that there's um, there's some really good stuff here and like They think about navigation switches is that it's there's a wide range of The navigation joysticks they're from like very tiny ones like this one is is very small This is you know, maybe eight millimeters by eight millimeters. It's there. These are very tiny And they're you know pick-and-play surface mount to like large Joysticks from like Greyhill with like a gigantic IDC connector. So They're all slightly different, you know, like here's this big M1 joystick and you can even see the The two pots on the side But we want that and then this is kind of a nice one. It's like a Vehicle, you know, like it's from a car navigation Another so another one, but it's very popular is this one. This is like, you know, the Xbox Style controller joystick a lot of you'll notice they originally were made and used in console games Or our phones or something and then the part became genericized enough that you can then get it Outside of that use case of like, you know, this is absolutely like a clone of like the Xbox controller joystick You know nubbin from the original like Xbox 360 You can get them now and they are two pots and a selector switch and they're very inexpensive. So You know, these are larger. They're not surface mount, but they're also good options. So let's look at the active Navigation switches and So, yeah, there's like different directionals there's ones that are like Hall effect we want Mechanical switch Yeah, just mechanical. I Think it'll be under that and then Thumbstick again is Usually analog we enjoy stick is usually something you grab with your hand and you move back and forth So you want navigation switch? Oh, I'll show you the what the one-axis ones are some fun ones Sorry, let's go. Let's let's stay stay on target. I'll show you that the navigation switch later. Okay, so Here's the here's all the options for navigation switches. So again There's like a miss mix match. There's like, you know, this ADA assistive device but let's Search by pricing So you can see all the different Cost versions so Unfortunately, there's a lot that don't have Photos so you'll have to check the the data sheet E-switch in particular makes a lot of these These are very slim style ones So they're not too dissimilar than the the NAS which I showed you but it's like very compact and you would have your own Yes, it's hard for a finger to do it. You want to have a mechanical add-on This one I've seen in a couple of projects that they're fairly inexpensive and they're surface-mountable and Then This is the one that like I said, this is the through-hole version of the Navigation switch so you can see that you you you can kind of sort of plug this into a breadboard. It's not quite breadboard friendly but you'd have to solder it in and then if you go down you'll see There's again a kind of a slim surface-mounted version and this is the one that I use so this is You can see the 360 on second So you can see This one has mounting nubs on it Which is actually kind of nice because it'll keep it from shearing off and there's a little like Clipping bits that if you want, you know, again make it mechanically stable so when people are pressing up and down It doesn't shear off of the PCB But if you just have six pads you can pick and place it It comes on a very thick tape But you know that as long as the pick-and-place nozzle can can get onto that actuator You're good to go and one thing that I thought was kind of neat is This is available in the Eagle CAD Kaikad library, sorry, they did you key Kaikad library, which I didn't know that they had So do check it out. They also have a bunch of tutorials So if you if you want Sean to teach you Kaikad or Kikad check out the tutorials there's also the CAD models the STP files and You can sometimes get the the if you're not using Kaikad you're using Altium Eagle whatever you can get the footprint from snap EDA or ultra librarian, which actually I've been using a lot lately I've been getting Footprints for parts even if I sometimes redraw the schematic symbol because they like I'd like to have the parts grouped in a Certain way I'll reuse the footprint because they did them math of getting the pads in the right location So check that out. Oh and another thing is them for a lot of these Nav switches you'll want to have a Cap on top for the navigation switch that I use there's a little rubber cap that we actually Sell it actually did appear down here Let me see Hold on There you go This black nubbin joystick, which did you key stocks on our behalf? Fits on top and even has a little like joystick symbol. It's not sold by e-switch It's actually a third party, but it fits very nicely on top of these five-way nav switches and kind of gives it a nice rubbery feel and you can see Here what it looks like it does it you know It is what the only thing that I didn't realize is it overlapped the reset button and so on the redesign I'm moving the reset button because when this was designed. I didn't have that rubber nubbin piece But then I added it later and then realized it was a little little in the way So that's the only thing to watch out for is it it does overlap your bike components However, like I said, I really like this nav switch Strongly recommend it. It's really great. It's very compact Takes up a lot less space than five tactile switches and I never had anyone say oh was confusing to use or difficult to use I think they're a kind of a joy For adding interface to your project That's great surge
