Already someone who iFixit able to get scarce devices before others. Suffice it to recall that they designed the iPhone 5 dismantling gallery even before the most agile Europeans had time to buy it. The better the scarcity of hours is felt Pebble, because they ended up in the hands of iFixit only now — almost two months after the start of shipment. We don’t say “start of sales” because not even all Kickstarter project holders have received their copies yet!
Whether you are waiting for your miracle watch or not, you will surely be interested to know what is inside it …
Kickstarter Edition. Sounds like a judgment. By the way, pay attention to the information at the bottom of the rear panel. Pebble can withstand pressure up to 5 atmospheres, i.e. they can swim in the pool.
As you can see in the previous two pictures, the case does not contain any screws. This is where the branded iOpener heating pad comes to the rescue — the same one that was used when disassembling the iPad mini and iPad 4th generation.
Water-resistance comes at a price: the front is coated with so much adhesive on the inside that it becomes impossible to open the watch without damaging the display. Decided to “repair” — say goodbye to the screen, like this.
Now at least some use from the top of the display will be only if you highlight it with a flashlight.
Click on the photo to get a closer look at each pixel:
By bending directly the layer of “electronic paper”, you will find LEDs for backlighting the display, as well as a flat light-conducting matrix. Here everything works the same as in the MacBook Pro, except that there are only three diodes.
Tricks with glue, it seems, are left behind — the electronic unit is just nested in a plastic frame with buttons and fastenings for straps.
But no — there is a certain amount of glue inside. In particular, an orange plume, coupled with a light-conducting matrix, “sits” on the glue.
There are a lot of components on the cable: all 4 buttons, all 3 LEDs, as well as a Bluetooth antenna. Here you can complain about the impossibility of replacing them separately, but who wants to change anything at all in this watch if the display still has to be sacrificed?
Under the light-conducting matrix, the upper side of the motherboard and battery is hidden.
Since the e‑paper display consumes almost nothing, the battery lasts up to 7 days. The battery voltage is 3.7 volts, the capacity is 130 milliamp-hours.
Top of motherboard:
• Red — Micron N25Q032A11ESE40F 32 MB Flash Memory Module;
• Orange — microcontroller ARM Cortex-M3 with a frequency of 120 MHz, STMicroelectronics STM32F205RE;
• Yellow — STMicroelectronics LIS3DH triaxial accelerometer.
The silver Bluetooth module bears the Panasonic marking “PAN1316” but…
… but in fact, the “heart” of the module is the Texas Instruments CC2560A chip. In the TI catalog, it appears as having no support for energy efficient Bluetooth 4.0. So what, the creators of Pebble mislead customers? Not at all. According to their own words, the chip has firmware from another controller, CC2564. Support for Bluetooth 4.0 is, even if it is not activated in the Pebble operating system.
There is nothing left — to get (or rather, squeeze out) buttons. For the sake of all the same water resistance, a rubber gasket is hidden under each of the buttons.
Since in order to disassemble the device you break it, there can be no talk of replacing any of the internal components. It’s bad, for example, that you can not replace the battery. From 6 to 10 years of work — and that’s it, it will just “fizzle out”. 6 years is not the best life for a good watch.
Rather than scoring 0 out of 10 on a repairability scale, iFixit decided not to assign a score at all. They would have had a good practice, and then, you see, the next clock would not have been broken. But how can you train here when it is extremely problematic to get even one copy of Pebble?
