@vortigont nope, I designed it for ESP8266 (with output connector going back to the panels, don't like either) I must admit even with no chip buffer on board it works so fine But if you want me to update mine it's no problem, the deal is if I put buffer on board, users may have trouble to solder these tiny SMD chip (because I want to keep the board tiny). Other way could be a board refresh with wiring for DMA with no buffer chip. Not sure these chip are mandatory with 1 or 2 panels, never had any issues without them. What's your though? |

Also found this nice DIY boards. Gerber files are available but not the project if any changes required. |

I always use the Boards made by. Brian Lough from tindie. Well made and great support |

Guys, took some time, got one, small, I2C, LDR, several way to power, 2 touch pad, and ESP32 in DMA mode of course, should do the job. Let me know if you see something strange or need something else. |

Ok here final version:
I will order a bunch and send you both one if you're interested. |

Guys, And, tadaaaaaa, this does work perfectly, LDR is fine, Touch PAD is fine (despite the fact it's under USB connector, so during testing not the easiest way) and I2C is fine also (holes are a bit too high to get full contact without solder) |

Well... since I just received the first working version of my PCBs, here is another option: Features:
A big thank you!! here to @hallard - your board has been the inspiration for this, and looking at the files you shared gave me the courage to attempt to build my own version. If you find any glaring errors/mistakes in the design, please let me know :) |

Hey guys, I've been working on a new board that will be open source when it's finished, the ESP32 Trinity. It's basically the I2S shield I have but with an ESP32 built in and much better support for being powered from USB. I'm currently testing what I hope is the final revision, I'll keep you posted! |

Haha, Oh yeah this is for designed for being assembled, my plan is to sell
them fully assembled so people can literally drop them into their matrix
For people interested in doing their own, and not interested in doing 0402
components the majority of the components, including the usb, are available
on jlc assembly service, I tested it a couple of months ago with an earlier
revision, but I don't know what stock levels are like now with the chip
shortage.
I kind of suck at assembling stuff (I'll be getting them made by someone
else) but even I was able to assemble them while on a live stream so it's
doable
(Very long live stream, don't expect people to watch it 😅)

@witnessmenow <https://github.com/witnessmenow> - While I'm a big fan of
your work (and this new board also seems great), I have to say... you seem
keen on adding challenges for the newbies (those of us who still solder
components by hand, and order PCBs in the smallest quantity possible, so
that automated assembly is not really an option :) ).
With my limited soldering skills, I'm getting chills just looking at that
USB connector... 😛

Got sick of those crappy dupont wires hanging around. So I was thinking it would be nice to have a PCB for an easy attaching to the 64x32 or 64x64 modules.
@hallard I saw you have a shield your repo. Does it works fine with I2S-DMA lib?
