 All right, get it get out of the vault here. What's in the vault today? I don't even know well you do because you Well you filmed it. Oh, yeah, we have the low power thing and then we have the Linux feather Yeah, I'm gonna play the first video and then we'll play the the Linux feather thing All right, Ada. What is this? Hey? I'm working on Rev C of my ESP 32 s2 feather and you might be wondering well Why did I have to revise this well? I kind of messed up the power stuff a little bit because I used I had the pull-up resistors connected to the three-volt line and I'm switching on and off the power But if you look here at my PPK output My power never really gets below about 720 microns which is really really high if you look at my oscilloscope the voltage never gets below 1.3 So I'm getting that leakage voltage from the two five 10k pull-ups They're kind of self-powering or backpowering the I scored C bus so with a rev C. I switched it to use a regulator So when I swap out to this rev C PCB with the exact same code First thing is you see that the voltage definitely goes between three volts and ground and on the power test Zoom in and a whole lot of people wanted a Linux feather. So here's a little bit of a preview This is an all-winner f1c200 s. It's the big sister of the f1c100 s This is one of those kind of famous all-in-one Linux on a chip type things It's actually got RAM built in all it needs is some external Nor flash and maybe an SD card and it's like a full Linux computer. It's not a very fast one But you know it may be enough to run some simple Python scripts So I thought it would be fun to design a feather. So I started the schematic capture With an SD card micro USB host Is that I'm starting to lay it out where you'd have a CP 2104 for the serial console Maybe we battery-powered went last a long time on a battery, but you know, you could win it on a battery Micro USB host out here and then you know start to get all the other components going and I think that micro SD card Will be on the bottom. So our Linux feather could be coming soon Okay, you were saying sorry. I was so excited. Um, I actually wanted to make a Linux feather for a really long time I got these media tech modules long time ago But you know, I what I like about this is It's very inexpensive and like there's people who've we use this chip There's like this Linux business card and there's bill who support for it So I thought it could be a good start because it's inexpensive enough that if it doesn't work out I don't I don't feel too bad about it. Okay, and that's top secret of the week
