ESP32 in Pre-Order

I keep wondering why everyone keeps looking at dma just for the speed. It not happening on the cpu is for me the most amazing part. I’ve got code steering a 144 neopixel string at 215 fps, basically continuously sending it data (>99% of the time), and hardly using any cpu cycles since it’s all DMA XD.

However it seems to be the Arduino methodology to use blocking functions most of the time.

For just 3,40€

Using DMA allows the processor to be more efficient and effectively multitask. However it seems to be the Arduino methodology to use blocking functions most of the time. But we are free to add non blocking functions to the libmaple core, I just don’t have time to write the code myself

I agree, NodeMCU (and similar variants) is the best way to play with esp8266 in 99% of cases (I exclude only the extra low powered applications).
I will be waiting the NodeMCU version for ESP32….

Agreed.

I am going to order some more of those NodeMCU clones as they worked fine with the Arduino IDE as soon as I selected the correct board type.

FYI
There is a kickstarter project for ESP32. As far as I can see it is the same layout as the NodeMCU board.
It is the same guy who tried to fund the EMW3165 board on KS.

https://www.kickstarter.com/projects/85 … =discovery

There is not only NodeMCU, but also Wemos-D1-Mini that works fine and has few shields such MicroSD.

@Erni Isnt that just a Kickstarter for the SDK? They just show of the NodeMCU Board with the ESP8266 and the dev board that got released with the ESP32

The way I read it, it is both.
But it is not a very clear description of the project.

This Kickstarter campaign is different from the exist software-only project, we provide not only source code but also hardware for backers to speedup development.

Another thing is that it is not likely to be funded, only about 7% raised in 37 days.

… and if you throw away the software, there is no need to pay twice the price of the real hardware price (I presume such boards will be priced around $9)

I’ve just noticed a different seller offering pre-order ESP-32 at aliexpress.

They cost $14 for two.

The item title, “2 pcs lot free shipping preorder esp8266 bluetooth wifi module esp32” is a bit worrying, but the blurb insists it is for ESP32.
They say delivery August, and ask for delivery to be extended o 90 days.

It looks like it is bare QFN48 chips, not modules. So the price isn’t justified !

Just received an email from AliExpress:

Status:
The seller has shipped your order

So the long trek begins … according to the new product page, 231 of these little suckers should be making their way out of China, so maybe my 2 will not be lonely until they hit U.S. Customs.

Yes, I’ve received the same notification yesterday.

Unfortunately I have not had any emails, and I may have made the mistake by extending the processing time, as it was about to expire on Monday, so I extended by 26 days.

I guess it doesnt really matter, I doubt I will use the module any time soon, as I have so many other ongoing projects

I finally received notification that my ESP32’s have been posted today.

So I won’t be receiving them until well after everyone else.

But until a few more people are using these, I suspect its going to be fairly tough to use them, especially the Bluetooth side of things

I do wonder if anybody has received their ESP32.

I made two orders (2×1 + 1×5) and got the following shipping confirmations
– on 7/15/16 for the 1×5 to be delivered in 15-40 days with dispute date on 9/13
– on 7/28/16 for the 2×1 to be delivered in 15-40 days with dispute date on 9/25

Cheers, Ollie

I don’t think anyone should receive them before you, as your items were posted a week before both Ray’s and Martin’s order.

What I find strange is why they didn’t post mine off on the same day as Ray’s (and Martin’s), rather than almost 3 weeks later.
