 What's up, okay? Well, this is a back in stock I'm even a revision, but I know people have been waiting like almost a year for these the feather and fours Which I'd love the samdi 51 chip is so powerful this Cortex m4 processor An FPU it's great We have a lot of products and projects that are using the samdi 51 series and we had a shipment of reels in And so we were able to get some feather and four expresses out the door So they're in stock. I think the last I checked we had about a thousand left I don't know when we're gonna get our next shipment of samdi 51. So if you Need the same the feather and four for something Please do get it soon. It's a temper soft you you can overclock the heck out of this. It's a great chip So yeah, this is your your fyi Next up we have a revision to the mlx 90s 393. The Lexus was hit very hard by the Um chip shortage and a lot of other sensors were not available But one version of this chip is available when I could get a reel of chips It's the same magnetometer But the i-squared c address is different. So I think the default used to be um o x o c Uh c in hex decimal and now it's 18 hex decimals. So it codes all the same the sensors the same Everything's the same except the default i-squared c address is different. Um, I thought it was worth it to Get them and you know, even though it's annoying to have to change the code examples to use a different address It's a little confusing. Uh, we do print it on the bags now. So the bag says it's address x 18 I thought it would be worth it just to get it back in stock So people could use this very nice very wide range magnetometer. All right start the show tonight besides you lady Our team our customers is The can feather So really i'm cranking out these rp20 40 boards with different peripherals on the right hand side I always wanted a board that had canvas built-in for easy plug-and-play No solder can projects And the rp20 40 Feather is a great place to start that. So it's got your classic rp20 40 chipset That's a dual core cortex m0 processor nice chip We pair that with eight megabytes of q-spy flash. So you'll use that for your program or your files That's kind of the middle top area there. You've got boot and reset button. So you can enter the boot loader and the Reset button of course you can reset whenever you want. It's got usb type c for data and uploading firmware and debugging Lipo battery built in with battery charging through usb c so you can take this project on the go There's a stem of qt port as well. And then in the you know, the feather pinout is standard It's got you know, 21 gpio pins and fourth more analog and Two iSquared c ports and two spi's and two ur. So it's got a lot of stuff going on with it Great for use with arduino micro python or circuit python. And then what I did is on the right hand side Um, I stuck a mcp 25 625, you know, like i've never heard of it. Yeah, it's basically a chip that has inside of it An mcp 25 15 which is a very very popular can controller plus a can transceiver It's just they just took those two chips and they squished it and they called it the 25 6 25 But the firmware you run on it is mcp 25 15 like firmware wise what the code you'd run for this chip controller Is like the most popular can controller. We've got arduino code for it. There's circuit python I think micro python also has code for it pretty much any programming language is going to have Code for that can controller because it's the most popular one in the world There's also a little Switch capped boost converter Above it that'll generate the five volts. So you can do a can bus with five volt power because you use a five volt power Sorry five volt logic Interface so the feather still running at 3.3 volts, but it has the five volt necessary to do that the can controlling There is a terminator a 120 ohm terminator Which you can disable by cutting that trace you need at least one termination on your can bus and then three terminal blocks low Ground and high so now you can plug into any can bus. There's a differential signal system your shared ground which is handy and then low and high and then you know Terminal screw on how many wires you want to shove in there and they're pre soldered So it's a new thing. I'm trying to get more boards where you don't have to do any soldering It's plug-and-play if you'd like to use it on a breadboard you can solder headers that comes with This photo shows it Yeah, we've tossed some headers in but you know, if you don't want to use the headers You just want to do can you're ready to go and again We've got Arduino and circuit python code and we also have uh u try f which is a software that runs For more that ones on the rp2040 it allows you to use your computer to connect a can device So it's like it acts as a usb to can bridge It's very handy and then of course if you want to add sensors So you want to get can node with sensors with stem qt port you can plug in almost any of the many hundreds of Stem qt or quick or picodev boards that come with the connector
