 Okay, this is like a little breakout board that will let you just connect step by QT and it has a pull-up resistors and LED And then I made two trinkets. So this is I have a lot of samd21 e18 to get rid of these And I was like, oh, you know, I should get back to the trinkets because we were making like a trinket week so This one has a samd21 with a recent button new pixel and sht45 which is like a really nice precision Temperature humidity sensor now for the final version I actually added a little cut out To isolate the sht45 because there's a little bit of self-heating going on. I also made a version with the sht41 Uh, this is um, somebody requested this they wanted a little fan simulator for like a computer to like simulate a pc fan So it's like, oh, yeah, the little like 555 timer with a little potentiometer could be useful So there's a little switch to switch the capacitor so you can do You know zero ish to 250 hertz or to 25 kilohertz you can do for audio on the right or you flip it You can do it for fans which are like about 100 hertz And then this is a usb host bff So using the max 3421 e and and on the go micro b connector You'll need like an on the go adapter But you can add usb host we're doing a lot more usb host stuff with the max 3421 We've got great arduino support and more circuit python support is hopefully coming soon So this could be you can make really tiny little usb host interface And then finally the great search two weeks ago We were looking because we were talking about the sht45 and I was like, well, what other humidity sensors out there We found this really cool ultra precise 0.5% Accurate, you know worlds of humidity sensors, so it'll break up board with again We'll cut out to give it some thermal isolation And that is this week's top secret
