This looks interesting

A larger broken out 8266 board. Looks like it would be a neat little IoT quick-start board for small applications.

Looks like the web page for it is here.

 

 

Here is another

Here.  This one has an led and photocell. No ch340 chip or usb either.

 

Great!

I was just going to ask if there were some breadboard friendly esp boards!

The Arduino environment has been added to the list of tools

From Hackaday.  Tools on Github.

One more type

This one has an antenna with it.

There is also a Linux VirtualBox image of a DELV env

This is the FULL ESP tool set.  It can be found here. you will of course need VirtualBox installed, but most of us probably use it already.

First stab at a bot with this board

I have this board with Nodemcu flashed on to it.  This is my draft obsical avoider bot code.  No network, as I want to see how the board performs doing simple bot functions like reading sensors and motor control.  Will move to PWM later this week, skipped it for now just to keep it simple and use less extra things in the code.

Here is the code so far.
