The Amazon Dash Button is a tiny piece of hardware that contains a single pushbutton, a WiFi module, and a nice, shiny corporate logo. Press the button, and products with that logo will be delivered to your house. An impressive bit of marketing, at least. With small, cheap WiFi modules like the ESP8266, it was only a matter of time until something an Amazon Dash clone was developed.
[deqing] created an ESP8266 Dash Button using the ESP-12 module, a button, a 3D printed case, and a pair of AA batteries. Electronically, it’s extremely simple; press the button, the ESP will wake up, request a URL, and put itself back to sleep. That’s all you need to do when you’re replicating the functionality of the Amazon Dash Button – the server will take care of the rest.
To configure the ESP8266, [dequng] is using the ESP-TOUCH app for Android, and setting up new functionality in this ESP button is as simple as putting a URL in the button’s Flash.
Not only is this a great build that has literally hundreds of different uses, it’s also not a breakout board for the ESP8266. It’s great that we’re finally seeing some builds using this cheap WiFi chip in the real world.
Obviously the actual Dash buttons include authentication that this one does not. We recently saw a teardown of the original hardware. We’re still waiting for in-depth analysis of the data squirted to the internet when an order is placed with it, though.
