Good morning all should we take a look inside this package from dhl. Well, i should say it's from jlc pcb via dhl, okay, uh. I need something to break this sellotape, so what we've got inside here? Well, it should be my chili paper boards, chili pepper boards. I should say: oh i've got a jigsaw puzzle, that's interesting, uh! I wonder if it's a different one to that jigsaw, puzzle and here are my boards.

Let's take a look inside yeah. I think it is a different one, because this says something a i manufacturing. What could that be - and here they are my chili pepper board, so chili pepper cp? These are the cp2102 uh usb to cereal adapters converters chips. Should we have a closer look at one of these? So there's one of the boards uh it's the cp scilabs cp2102 got a couple of caps up near the usb connector.

Now i've got those usb connectors. We'll have a look at that in a minute. We've got leds uh, three of them, one at the top, which is power two at the bottom, i believe, are the rts and dtr, no sorry the tx and rx leds um. Now i have noticed - and i'm not going to hide all this stuff away.

There's a missing cap on the second board. Next to the usb connector, it clearly fell off at some point. It is what it is um. It doesn't actually concern me too much because i've got more boards than i'm ever likely to use, but there it is defects.

Can occur, and there is one now i went to ebay - to buy some of these through-hole usb mini connectors and i've been having a lot of trouble with ebay. Recently, it seems almost everything i buy is either wrong. Broken uh doesn't turn up or something along those lines, but these ones are actually wrong because the picture on the ebay listing had four mounting points and through hole pins. These only got two mounting points now it may not matter.

I'm hoping this fits. So, let's have a look: let's put the through holes through the through holes, yeah, that's fine! The two mounting points um and the through-hole pins all match in terms of sort of relative distances and two mounting points is probably enough, and maybe that's why the seller felt he could substitute these for the ones with four mounting points. But it's not actually what i bought, but i think on this occasion i will accept this because that does fit. It fits fine once that's soldered in on those front two mounting points and on the five uh sort of connection pins.

I think that will be strong enough, i'm not going to make a big fuss. So let's get that connector soldered in let's also put on a six pin. I think i'll go for a right angle, header there and well see if it works. Here's the rest of the jigsaw puzzle for the solder mask room, but what i really wanted was a couple of these puzzle pieces, maybe three uh to stack on top of each other.

Two might work to offset the height of this yeah. That looks about right, uh to solder in my usb mini b, connector right, let's solder, this connector in and just clean the tip and um. Let's do the mounting points first, i want to try and do it without tipping everything over which will lose my nice alignment and now, let's try doing the five connector pins yeah. That seems to be going quite well probably easier than i could do surface mount pins.

That one didn't flow quite so well, oh, is that ground, maybe yes, i seem to be having trouble heating that that's probably the ground pin. I might check how big the spokes were on that one and now, let's solder in a six pin right angle, header which one's ground on here, i think it's the second one up. Let's see if that's more difficult, sorry, yes, it is always more difficult to solder. The grounded pin because all the heat gets pulled out into the copper area.

These look like tx and rx rts and dtr, probably at that far end. Okay, that's all sorted ready to test. So there we are my chili pepper, usb to serial board and an arduino pro mini. I want a six-way connector, well five-way, actually, because i don't need two resets uh.

I think i don't know what the black wire on here is black. Where does that go? Maybe it's ground, it's the green one i'll get in closer yeah that one top right, marked grn. You can see that very close to it is that differentiator 100n capacitor just under where it says tx, and that is the reset input for the arduino pro mini, so that will come from well, i think rts or dtr on my chili pepper. Let's try it.

I suppose the first thing i should do is connect the chili pepper to my usb mini cable to see whether it explodes well, it didn't explode. The blue led has come on. Oh that's an o603, so i do know where an o603 is um. Actually, i have to go back and find that one, because on my later board i couldn't find it, but anyway that's it um yeah and i got the windows ding dong, so that looks like it's registered itself on my pc.

What we need to do now is try and download a blinky sketch right, six-way, cable. I think what i'll do is i'll. Just stick it onto the six pins of this, but i'm not going to use them all. So i won't use that's proving tricky to get on.

Oh no, there it goes. I won't use the blk up at that end. I'll use the grn, although that's now brown at this end, so let's try and find how that connects to this. So this first one brown is the uh reset so i'll put that on dtr.

For now, then the next pin up is tx. So oh does that go to rx on my usb to serial. I think it does well we'll try that and see if it works. Uh the next one up, presumably is rx.

That's on the orange and that'll go to my tx, like so uh. Vcc then, is on yellow, oh and that's the other way around. On my board, i didn't bother to harmonize that with the pro mini so yeah. It's back to front whatever and ground is here on green, so i'll put that on my ground point and it goes if i can get that in there and the pro mini has fired up and there is a blink sketch on it already.

So what i'll? Probably do is try and download a double blink sketch. Let's give it a try. So here we are in arduino ide now i know that the last board i used was the esp32. So i've got to change that uh boards manager, arduino avr boards.

We want a pro mini, don't we? Where is it? Oh pro or pro mini? That's right! Oh that's! Taking a while processor! Oh i don't know, but i'll assume. It's 5 volt. 16 megahertz! That's fine port! Oh that's appeared on con 5.. Oh! Yes! Now! That's probably because the esp esp32 board has a cp2102 on it, and this uh chili pepper board also has a cp2102 and it basically saw the same thing and said: oh, it must be com5, then so that's fine com5.

Now what i'll do is i'll? Just speed up the flash: let's do 250 uh on and 250 off uh. Oh that's going to overwrite my blink program. Well, it doesn't really matter. Does it? I suppose i could just save as let's save as uh.

So i've saved it as blink fast because that will blink fast. That should be everything i need and my board is set up. So let's upload that make sure it compiles i'll bring the compilation thing up. That's compiling the sketch seems to take an age on this pc, particularly when i'm running obs i'll come back when it's done actually.

More importantly, i want to see whether it triggers my tx and rx lights. The compilation is going through, let's point at my tx and rx lights. Oh it's uploading! Oh there they go. Oh look at that and there's my fast blink.

Yes, my tx and rx lights came on and they were nice and bright. Actually. That blue led is quite dim, but that's because it's got a 222 resistor in there what's that 2k2, and i think these two leds have got one case. Oh that works quite nicely.

Should we do that again, compile and upload that should go quicker now, because certain compilation stuff will be in memory here we go flickery flickery flickering and it's done well, it all works. What can you say when it all works? Okay? Well, i can't, i can't think of anything else to do because it works, so let's just go even faster 100 on time and 100 off time, that'll blink five times a second. Let's do the whole thing on camera, this time we'll do the compile and upload. Oh and i'll set the other camera running, because i want to capture the um tx and rx lights, so i'm recording on both things now, all the tier, oh, yes, they happen very quickly.

Oh and it's flashing really fast. It all happens rather quickly because it is a very short sketch, because i want to capture the um tx and rx lights, so i'm recording on both things now all the tin. Oh yes, they happen very quickly. Oh and it's flashing really fast.

It all happens rather quickly because it is a very short sketch. Well, i'm very pleased, my chili pepper board is an unmitigated success. It just works, so i've got the trixo in production, which is the uh ch340, and i've got my um pro minty coming, which is my sort of square. It's going to be green, my square almost like a pro mini, but with connectors so that i can use all this gubbins they're coming.

Um just want to alert you to a couple of things: i've seen on jlc, pcb's, uh various website and uh, twitter and whatnot. So, on jlc pcb's website um, i noticed this has come up. It's a new arrival, two dollars for aluminium, it's not aluminium! Is it it's aluminum for well aluminium? For me, aluminum, perhaps for you boards, one layer, 3000 volt breakdown, one watt per milli, kelvin thermal conductivity, is what it says: uh minimum drill size, one millimeter and minimum slot width 1.6 millimeters. So i'm definitely going to have a go, an aluminium board.

I think that'd be a lot of fun uh. I suppose the obvious thing to put on there is leds, so we'll do a bit of that that'll be a lot um now. The other thing is something i saw on twitter. So let's have a look at that and uh.

Yes, it was this tweet here from jrc pcb on june 25th, as you guys wish. Rp 2040 is available in the jlc smt parts library, so you can now have the raspberry pi rp 2040 soc. I suppose it is put on a board without having to do your own soldering. Jlc pcb will do that for you, so i will definitely have to have a bit of a play with that.

I suppose i'm gon na have to do a very quick learning curve. Uh introduction might introduce myself to the rp2040. I think it's the raspberry pi pico. Isn't it the board that has that chip on, but once i've introduced myself to that yeah i can build my own rp2040 boards.

So that's it really. I can't drag this out any longer because well, you can't drag out a video when something works. Uh yeah, i'm very pleased with my chili pepper cp2102 board. What can i, what more can i say, cheerio.
