Production Building?

[hughesdo]

Is anyone building these is a production manner? I've been monitoring this site for over a year. I would simply like to know if I can buy a pre-built one of these that is semi professionally built. I've made a couple of half hearted attempts to build this myself with varying degrees of success. Mainly failing at the TTF screens. At any rate I give up! I would just like to see a fully populated one to buy pre-built with software that will compile and included so that I can still "play" with the code.

I am in the process on designing a PCB. It should be ready in 1 - 4 months. Will link it when I'm done.

Can you also email @.*** ?? Thanks!! Do you have a URL I can bookmark?

Lilygo.cn used to produce this board http://www.lilygo.cn/prod_view.aspx?TypeId=50032&Id=1157&FId=t3:50032:3 https://www.aliexpress.com/item/32848882218.html you can still find them around https://www.aliexpress.com/item/1005002036937632.html?spm=a2g0o.productlist.0.0.ad4c412eskzmie&algo_pvid=d494b3f3-ac0a-4314-8575-e768cc391087&algo_exp_id=d494b3f3-ac0a-4314-8575-e768cc391087-1 (not sure why they still don't produce them if there was an issue with the board) Edzelf said he is trying to add that I2S chipset for ver 2 so that would basically be the full package. My only issue with it was that it didn't use a prepackaged esp32 with the rf shielding can on top and the latest ESP32 ECO V3 chipset.

I think we need to spec some kind of feature list that the new unit(pcb) needs and do an opensource pcb. For me it'll need to have a class D amp 5W - 30W, be able to run from 12V, an monochrome OLED display, a rotary dial and some buttons. Is the ESP32 ECO V3 the dual core ESP32?

There was a bug in the silicon that caused glitches with PSRAM and a few other things all they did was fix the silicon for these issues document about it below but it's still the same ESP32.
