More Sparkle Motion testing - 24V Neon Neopixel Tubes ✨🌈

This chonky neopixel tube is a treat with full, smooth color all the way around - but it's also a real pain to drive, given it requires 24V power. Or at least it would be if we didn't have this Sparkle Motion

Adafruit Sparkle Motion - All-In-One WLED and xLights Board

Coming soon! We're designing a board for using WLED - and we want to make like the bestest board in the wholeworld. Our resident me

board we are testing! With USB PD support, it's easy to plug the board into a USB C laptop power supply that can provide 20V at up to 5A - even though it's under 24V, we've found the LEDs are just as bright. Looks great, we're going to keep testing and get these boards ordered, hopefully before the year's end!

PCB of the day! HUSB238 USB PD Sink Breakout 🔌🔋💡

USB C has a nifty power management system where, by default, you can get a classic 5V at 1A power out from a power supply or port, but with some fancy twiddling, you can request higher voltages and currents. We've always wanted a simple breakout that could get you a range of voltages using just jumper pads, but we only had a little luck with IP2721. Then we found this chip - the HUSB238 https://en.hynetek.com/pdsink.html - used in a USB-to-DC cable, which seems perfect! It can do 5V to 20V with just a resistor setting and set the current. There's also an I2C interface that can be used to set them if the settings are persistent - we'll have to try it out. There's a library here if you want to see what the registers are like https://github.com/ltyridium/HUSB238-lib. Here's our draft for a breakout design.

PCB of the day! Requiem for a 5.1K CC resistor 🔌💡🔧

We have a few gadgets around the house that, despite having a USB type C connector, do not abide by the USB C power delivery specification! They leave off or mis-connect the two 5.1K resistors required to tell a USB PD wall adapter that they want 5V 1A power, a common issue because the devices work fine with a USB A to C cable, and only Macbooks seem picky about this stuff: cheap power supplies blast 5V and call it a day. This doo-hickey is a solution. It has two USB sockets nestled back-to-back, and instead of connecting the CC lines through, each half has its own dedicated resistor set. It makes for an excellent symmetrical design. Pair it with a short USB C-C cable to create an inline extender. We considered having one side be a plug, but the SMT-able plug connectors seemed like they needed to be more mechanically stable.

HUSB238 is a smart USB PD chip 🔌💡🔋

We wrote a driver this week for the HUSB238 USB PD sink chip https://blog.adafruit.com/2022/05/04/plug-n-play-usb-type-c-dummy-pd/ - this IC is neat in that you can either use jumpers (really, resistor selection) to set the desired PD voltage and current ooooor you can use I2C for dynamic querying and setting. we have a wall adapter that can provide almost-all-PD voltages: 5/9/12/15/20 only 18 is skipped. The HUSB plugs into the USB C cable and, over the CC lines, will negotiate the PD request and commands. For example, we can ask what voltages are available and then iterate over the options here: a multimeter displays the output voltage to prove it works! This can be a handy chip for projects where you need a lot more than 5V @ 2A power: this adapter can give up to 20V at 5A - yes 100W over USB C - and you could buck that down to get a toooon of current at 5V or 12V if that's needed. Arduino library and example code is here https://github.com/adafruit/Adafruit_HUSB238 . This is also one of the first shipping boards using an OpenAI ChatGPT assisted library https://chat.openai.com/share/d05c963d-b610-4eef-ad98-05656a33e118 https://chat.openai.com/share/a276ce74-f810-4dba-a324-e9fd1545085f
