 early data. What is this? This is an HUSB238 breakup board. This is an interesting chip here. It can either set the power delivery voltage from USB-C using jumpers for current and voltage over here, or it can do it over I squared C. So I've written a little driver that's running on the Metro mini and what it's doing is it's iterating on every voltage available. So 12 volts, 15 volts, 20 volts, and then back down to 5 volts. And on the other side of the USB-C cable is this, you know, nice power adapter. And this is the one that can provide 5, 9, 12, 15, and 20. So on the computer I've got a little driver that I wrote and it's testing out each voltage and it can communicate and see like what are available and how much current is available. So this driver is working really well and this is really nice because not only can you use jumpers if you want to like hard-code it, but if you want to dynamically change the voltages you can use this Arduino driver. So coming to the Adafruit shop soon.
