The Spectacles’ internal hardware is stored in two compartments mounted on either side of the frame, above and behind the lenses. On the left, are the record button, indicator lights and charging connector. On the right, are the camera and microphone.

Cracking Open Snapchat Spectacles: LED record indicator

A series of LEDs on the front of the Spectacles let people know that they’re being recorded. There’s also an LED on the inside of the frames that let the wearer know when they are recording and when the recording is about to stop.

When you push a button on the case, an LED indicator light tells you how much charge the battery has.

Cracking Open Snapchat Spectacles: Removing the temples

Before doing any actual cracking, I removed the temples, which I was shocked to learn is the official name for the arms on a pair of glasses that run alongside your head and over your ears.

Cracking Open Snapchat Spectacles: Loosening the adhesive on the hardware covers

Using a heat gun, a variety of plastic tools and a universal opener (better known as my thumbnail), I next removed the glued-on plastic covers that protect the Spectacles’ high-tech innards.

Tiny metal plates embedded in the plastic cover that protects the main circuit boards appear to be heat sinks with blue thermal paste on them.

Cracking Open Snapchat Spectacles: Removing the battery

The battery, charging circuitry, LED indicator lights and record button contact are located in the left compartment. Luckily most of the internal components are held in places with screws, which were easily removed with a Torx T1 or T3 bit.

Cracking Open Snapchat Spectacles: 3.8V 137mAh/0.52Wh Li-ion battery

The Spectacles’ 0.52Wh battery might seem puny compared to other prominent wearables like the Apple Watch Series 2 (1.03Wh battery), Moto 360 (1.1Wh battery) or Google Glass Explorer Edition (2.1Wh battery).

Cracking Open Snapchat Spectacles: Removing the wireless circuit board

After detaching the thin cable that runs through the frame, removed several screws that hold the internal components in place, and then lifted out two tiny boards boards that are sandwiched together.

Cracking Open Snapchat Spectacles: Nordic Semiconductor nRF51822 Bluetooth low energy and 2.4GHz SoC

The most prominent chip on these boards is the including the Nordic Semiconductor nRF51822 that provides wireless connectivity.

Cracking Open Snapchat Spectacles: Circuit board

Cracking Open Snapchat Spectacles: Kingston 04EPOP04-EL3BM627 ePOP memory module (contains 4GB of eMMC + 4Gb of LPDDR3 DRAM)

The Spectacles have a Kingston 04EPOP04-EL3BM627 ePOP memory module which contains 4GB of eMMC + 4Gb of LPDDR3 DRAM.

Cracking Open Snapchat Spectacles: Ambarella A12-N-A2-RH wearable camera SOC

The main circuit board contains the Ambarella A12 camera system-on-chip (SoC), with embedded ARM Cortex A9 CPU, and a Kingston 04EPOP04-EL3BM627 memory chip (not shown).

Ambarella, the company that makes the video processor inside the Spectacles, also makes video chips for wearable cameras (including those from GoPro), car dashcams, aerial drones, and VR cameras. In fact, a version of the A12 SoC is used in police body cameras.

Cracking Open Snapchat Spectacles: HD camera with 115-degree lens

The HD camera on the Spectacles has a 115-degree lens designed to produce circular video the more closely replicates what we see with our eyes than the rectangular video most cameras produce.

Cracking Open Snapchat Spectacles: Microphone

The microphone is mounted to the side of the camera on the same metal bracket.

Cracking Open Snapchat Spectacles: Thin ribbon cable runs through the frames

A thin ribbon cable runs through the frames across the bridge of the glasses and connects the electronic components on either side of the Spectacles.

Cracking Open Snapchat Spectacles: Completely disassembled

The entire teardown took about 45 minutes, at least 20 of which I spent carefully heating and removing the various the glued-on components.
