"Amazon says Portlanders have used [Prime Now] to purchase tens of thousands of items, the most popular being sparkling water, organic macaroni and cheese, and the Kindle Paperwhite."
At the heart of the Dash is a USI (Avnet) 850101. The 850101 is a combination wireless module (Broadcom BCM43362) and micro controller (ST Microelectronics STM32F205). This makes the Dash capable of connecting to 802.11 b/g/n networks with its 120MHz ARM Cortex-M3 processor. It also happens to be exactly the same chip used inside the $19 Spark Photon.
