My 99-cent Amazon Dash Button arrived today and I was excited to get a look at it. The little device feels very sturdy. Unfortunately, my wife told me she had no interest in ordering laundry detergent by pressing a button, so I had to figure out what to do with it.
I decided to open it up and do a teardown. For science, of course.
The FCC ID is 2ACBE-0610. Documents in the FCC filing appears to confirm that this is indeed an 802.11b/g/n device (not Bluetooth, as initially thought).
It has a large white button with a red/green LED.
FCC ID: 2ACBE-610 / Model JK76PL
Removing the back of the case reveals a Li-ion AAA battery
Can anyone identify the wireless radio chip?
Other interesting components?
Whether or not you find it useful to order your laundry detergent at the touch of a button, this has to be one of the least expensive 802.11 devices ever produced.
I wonder what the actual component costs are? I think it’s safe to say more than the 99 cents that I paid for it.
It looks like Matthew Witheiler @ Bit of Cents has figured it out:
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.
