California Proposition 65 Warning WARNING: This product can expose you to chemicals including Nickel which is known to the State of California to cause cancer and which is known to the State of California to cause birth defects and/or other reproductive harm. For more information, go to www.P65Warnings.ca.gov
Click to see Why is this here? As of August 2018 the State of California has changed the requirements of the “Prop 65” law. We now must list on our website any possible chemicals the can cause cancer, birth defects or reproductive problem.

As an example:
   ABS plastic contains styrene
   PVC wire insulation can contain Di(2-ethylhexyl)phthalate (DEHP)
   electrolytic capacitors can contain Ethylene glycol
   Brass can contain Lead
   flame retardant pc boards can contain Tetrabromobisphenol A (TBBPA)
   Aluminum alloys can contain Chromium

To put it simply we are a small company and do not have the resources to test every single part, so we list every thing as hazardous. Please recycle all electronic parts responsibly and under no circumstance eat, drink or smoke these parts and wash your hands after touching!

Amazing Little MCU Board with Wifi
These things would be better called MCU controller board with built in wifi. The Wifi Module thing kindof implies that you need another arduino to drive it. NOT SO. They have an 80 MHz 32 bit processor on them. You can pull up the Arduino IDE and select Generic ESP8366 and then you can program them in C++ like any other arduino. You will need a USB to TTL Serial converter and a few wiring jumpers to program it. I have one running a web server right now. One gripe is that these are not 4MB, but rather 4 M-bit or 512K flash, but if you really need to, you can desolder the 512K flash and replace it with a real 4MB 32Mbit flash from the 25Q family. Also, they are 3.3V and not 5V. If you forget, they will blow out.

not recommended for beginners
This is a very solid product but I would not recommend it do beginners, the setup and execution are very advanced.
