I saw this in a Bangood email...  after reading the description, it looks like this could be used with Arduino.   Would be a cool module if it could work, IMHO.

Anyone know more about this?

Can it be used with Arduino?  If so, anymore data, experiences, etc.  Good/Bad...

If so, how?

Thank you in advance...

Then, I found THIS one...  Looks more promising...  Any good?  More "How to use" anywhere?

The ESP32 is just an Arduino on steroids. You'll need to add the ESP repository to your preferences>additional board manger in the arduino IDE, then it will turn up in your boards listing. It has a few minor changes to arduino, but a bunch of examples will be added to your IDE menu to help with that. The ESP 32 is my dev platform of choice. It just blows the Ardiuno out of the water, built in wifi/Bluetooth/touch sensors/hall effect sensor, 4mb (expandable) and filesystem, 2-core 32 bit processor and ultralow power co-processor. The wemos D1 dev board is a good starting point for 8266 (a weaker version of the ESP32), and small and cheap enough to be used in final products. 
The products you show are meant for Expressifs ESP Who/ESP Eye AI image recognition (thought they probably don't have the 4Mb + required to do it well).

WOW!

Is this module for an ESP board like an Arduino UNO or is it a standalone unit?

Would I have to get more ESP stuff to use this Module?

Thank you...  Sounds the ESP32 is very powerful...  and it can be programmed just like the Arduino?

It's a standalone unit that would replace your Arduino, and behaves in pretty much the same way, most code that runs on an Uno will run without modification*, in exactly the same manner on the ESP. It's pretty much like switching between an Uno and a Mega, change the board type/com port and you are good to go. 

Be aware that those camera modules will eat quite a few of the I/O pins. It might be an idea to take a look at the Wemos d1 mini, NodeMCU  (ESP2866) or  ESP32 WROOM (ESP32) development boards if you have no particular camera requirement (most of the available documentation is for those boards, but a lot of it can be applied to any ESP based board). 

* There are some minor changes to the pin assignments, but the ESP has I2C, SPI, analogue and all the other usual pins (I *think* all the ESP pins are software defined) and digital pins just like the Uno.

A good link to read up on the various ESP 32 dev boards:-

Thank you very much for the information...  It's a little more than I thought it would be...
