 Every single week ladies years are power of engineering to help you. Yes, you find all the things you want online at digikey.com Lady Eta, what are you looking for this week? Okay this week? So let's go to the overhead and I'll show what I was just showing which is Hacking this electronic kids toy And I'm plugging in an I2S amplifier into my ESP 32 board to get a nice quality audio Build demo again Okay, so The I2S audio sounds really good the speaker sounds really good it runs off of a charger batteries because I'm using a boost converter everything's great and The connector that I'm using on this board is a molex picoblade, and I realized I hadn't covered molex picoblades before on the show and I wanted to show them off and So let me demo why you'd want to use a picoblade. So this is my Second Let me grab I've got like okay, so we got like a funhouse board here. So this funhouse board has JST three-pin connectors on the side and Also has a stem IQT. So the semi-qt is JST SH, which is not you know, I'm not a bad character, but the very common Connector you're gonna see in the real world is the 1.25 millimeter pitch Molex picoblade and it what's nice about it is the pico is is is a Fine word to use for it because you can see how thin it is compared to this JST pH It's a very skinny connector, but it's nice and solid It's from molex and they make really good stuff The blade is because the contacts actually if you look carefully, they're kind of bladed You know, they're not pins They're flat and that actually makes them also much more durable Especially if you have like a lot of cycles connected and disconnect They don't bend. I've never had a picoblade bend or crack on me I have had pins on other connectors You know that if you don't get it quite right something catches they'll bend inside the contact of these Don't seem to another thing I really like is that there's this little cut out here So you can see that the contacts are there and straight so you can you know before you connect something and then this is the Contacts which is the Sockets which go into in this case the speaker So let's go to the computer So like I said, they're called molex picoblade now one thing I noticed while Searching is that there's actually Well, first off, did you keep change their front page? So check that out new products is kind of nice is what I use for an MPI So molex picoblade Okay, so there's a lot because they're gonna be cable assemblies and they're gonna be connectors so we want to go to header mail pins because that's what goes on the PCB and You know, let's say we want two positions active and Surface mount right angle because that goes out the end and Let's just say in stock So, yeah, these are some of the contacts that you use what I like is that it's like you only get three and the three are all Slightly different So this is the series the five three two sixty one This is the this is what I tend to use. This is the tinned version You're feeling fancy you want gold Gold plated contacts. They're more expensive But they will resist oxidization more and then There's also a nice 360 And they did a really good job getting a lot of photos of this. You can really see all the contacts. I can see like nice thick contacts here that blade again a lot of mechanical stability over here and then I really like On the detail here Zoom in a lot of mechanical stability again. I've never had these fail or pull off. They're they're really really solid connectors So this is the part I recommend using I mean you can use the gold plated one or you can use the silver or the tin plate one However, you probably also want matching cables to go with it which you can also get so if you click on the series That'll take you to Like everything in that series. You're like, oh, I want like five pins or six pins. It'll give you everything in that series and then you could also go to molex picot blade and Search for cable assemblies, which I always recommend so you can you know get Let me show you one more thing. Sorry In addition to you can click on that if you go down to the bottom here Um You can find oh Under featured product if they featured it, what's really nice is they have like this kind of descriptive text that tells you about it Not all products have this but like most series a large series of products do So in this case, it kind of tells you, you know, what's used for One amp of current Which is a lot again. That's you know compared to Jcsh, which I think is like 340 milliamps, so it's quite a lot of current which is why I really like it for speakers You can get contacts You know connectors housings and then crimpers if you are going to do your own Cable assemblies, you know get the official crimper Or get like a really nice like engineer crimper Don't use a pair of pliers because otherwise you're gonna be sad You're gonna you're not gonna have a good time if you don't have a good crimper But if you don't want to crimp, I do always recommend getting pre-made cable assemblies They're not that expensive especially, you know, considering you get them the next day And then of course when you go into production, you can either use the pre-made assemblies or like contact your cable house And they'll make you picablaid connectors with any Combo, but what's nice is that like, you know any number of circuits almost any length. So, you know, say we want a two-pin cable And let's see what's available here 450 millimeters 150 100 Little extend those very handy to have these little extenders 450 millimeters and then, you know, just pigtails if you need them and socket pigtails and plug pigtails. There's actually another interesting thing about picablaid is Some cable systems again, like the JSTSH. I don't believe it. I've never seen JSTSH Freehanging, but what I like about Molex picoblaid is that they have PCB mount vertical right angle and then, you know cable connects and then they have freehanging Connects as well. So again, you can do the extenders or you can just have like if you want these for freehang I really like that this cable series for that reason. And again, like compared to the JST PHs are much smaller, but they can carry a lot of current good for wearables leds speakers like av stuff Then while this whole series is my You know my pic this particular product Would be my choice for The great search And that's a great search
