E dismantling: buy a Wami smart watch, come see the value yo

Introduction: Recently, the mobile phone is disassembled for the small partners. Is it true that the dismantling of the small e is not only in the mobile phone, but also in various smart wearable devices! Near the Spring Festival, we will review the Huami smart watch released in 2018. Let's see how it differs from previous sports smart watches?

Recently, the mobile phone is disassembled for the small partners. Is it true that the dismantling of the small e is not only in the mobile phone, but also in various smart wearable devices! Near the Spring Festival, we will review the Huami smart watch released in 2018. Let's see how it differs from previous sports smart watches?

Configuration list

Still the same, first look at the basic configuration of the device (the following parameters are the small E home engineer brother test data, or different from the official data).

SoC: Ingenic M200 dual-core processor

screen: 1.30-inch AMOLED screen 丨360x360 resolution 丨 screen accounted for 87%

Storage: 512M memory 4GB flash memory [ 123]

Battery: 390mAh lithium-ion battery

Features: voice assistant l NFC function l can make, receive calls and receive text messages l new generation of high-precision optical sensor l Corning Gorilla 3 protective glass

Disassembly steps

The case and the back are glued with waterproof glue. The hot air gun is used to heat the thin seam of the back shell and use the crowbar to pry the back shell along the slit. The back shell is made of TD1-2. After disassembly, you can see that the back shell and the inner support are respectively placed with foam and silicone sleeves. In addition to protection, it can also play a waterproof effect.

Then remove the screws attached to the main board and the inner support to remove the motherboard and battery easily. The motherboard and the battery are adhered through the transparent double-sided adhesive, which is also very easy to remove.

Firstly, the inner support is processed, and the microphone and the soft board and the vibrator on the inner support are removed, and the vibrator is sleeved with a silicone sleeve.

The heart rate sensor cover and the rear case are fixed by foam rubber. The underside of the earpiece is made of silicone for waterproofing.

The heart rate sensor soft board manufacturer used in this smart watch is QOGRI.

辗 看 look at the screen, the screen and the case are connected by glue. The screen uses a crystal 1.3-inch AMOLED screen with a resolution of 360x360.

Summary information

This smart watch is shared with 4 screws. Although it is not attributed to sports watches, the whole watch is still waterproof, and silicone or waterproof plastic sheets are used in the speakers and earpieces of the whole table. The overall dustproof and waterproof rating has reached IP68. In addition to this, there are a lot of foam pads on the rear case to protect the BTB interface. The overall structure is stable, but the disassembly is simpler.

In the basic configuration part, many small partners found that the data provided by Xiao e was inferior to the official website data. Don't worry, Xiao e will sort out the source and measurement method of our data in the near future. Please stay tuned!
