“he Amazon Dash button is a tiny device that orders products from Amazon.com at the press of a button. It’s designed to be put wherever you store consumeables like paper towels, trash bags, etc. so that you can easily order more when they run out. The Dash is great at what it’s designed to do, but did you know inside the Dash is a powerful ARM Cortex-M3 processor and WiFi module that are very similar to wireless development boards like the Particle Photon? You’ll even find there are easily accessible test pads on the Dash which allow you to reprogram its CPU and turn it into your own $5 internet button! This guide will explore how to take apart the Dash and reprogram its CPU to run your own code.”
