First test of my 8x parallel output ESP32 FeatherWing worked great!
This was with just 400 LEDs, I’ll be testing with 800 tomorrow, and with 1,600 when my next order comes in! 
Thanks to @Sam_Guyer and everyone else that worked on this!

Nice job on this board Jason.
WOW, just wow!!! I want to buy an assembled version, do you sell it? Not yet there for soldering as my skills are still left too that of a monkey throwing feces.
Thanks @Darren_Hedlund ! The bare PCBs will be on Tindie soon. I’ll be adding a kit that includes all the required components. I could do a preassembled one, but it requires a lot of soldering, takes an hour or two, might not be cheap. 
Wow, looks great. Just seeing a whole bunch of LEDs in rainbow colors makes me happy!
@Jason_Coon I will try to do the soldering. Let me know when you have it ready on Tindie, I might just have to order many. lol
Side Note: Last night, I was hacking and slashing through your esp8266-fastled-webserver. Adding more graidents, new routines, and soo much fun. Bravo on the newest version.
@Sam_Guyer Makes me want to buy more and more lights.
Did someone say ‘moar lights’?! Here’s 800.

It will be great for building ledstrip matrix , any idea if Sam’s patch and newer version will be available official in arduino update libs any soon ?
@Jason_Coon HOW THE??? You are a magician, you are. I want that whole bloody setup! How are you handling the power? Hurry up and add this to your Tindie. (I’m So feakin Jealous)
Not sure, @Nikolay_Hristov , but it’s easy enough to switch for now, until a pull request gets submitted and merged.
Lol, thanks @Darren_Hedlund , but Daniel, Mark, Sam, etc are the real wizards. I’ve just learned their spells. The board has a spot for a barrel jack power connector. It’s rated for 2.5A, and can be used to distribute a small amount of power. I’ve soldered 8 sets of 5v, GND, and data wires directly to the PCB. I’ve set FastLED to automatically limit the brightness to keep peak power usage below 2.5A. I’ve tried setting it to 4A, and am not seeing any heat or other issues. I have a 20A power supply, and although I strongly recommend against it, I’m going to test this (with extinguisher in hand) until it bursts into flames. For large numbers of LEDs, you should distribute power directly to the LEDs, not power them through the PCB.
@Jason_Coon Just so nice and clean compared to my huge 300w 6v 60a power supply. I am amazed at how clean everything is, and that is the direction I want to go as well.
@Darren_Hedlund there are two PCBs listed on Tindie now: https://www.tindie.com/products/jasoncoon/octo-level-shifter-featherwing
@Jason_Coon Ordering!!!
@Jason_Coon You should also include the parts to go with it as a full DIY kit.
@Darren_Hedlund yeah, will do. I hope to have that up tomorrow. I can let you know when I do if you’d rather wait for it.
@Jason_Coon I have till Christmas so I think I got some time… LOL
Already ordered the board (I need the practice big time) and will order the parts when you have them listed as well.
Now just digging back into your esp8266-fastled-webserver program to figure this data load thing out…
What’s the small 0.10µF Capacitor for? Just to clean up power to the 74hct245? I might need to order one myself
@Thomas_Balu_Walter yeah, it’s a decoupling capacitor, recommended by the datasheet.
@Jason_Coon Your boards are made superbly with high quality, wow! I just ordered another but this time with the components. Fantastic job! P.S. my soldering skills really really suck but working on it.
Seriously, order his stuff! https://www.tindie.com/products/jasoncoon/octo-level-shifter-featherwing/
