Entry-level wearable devices, love is never easy

In 2014, wearable devices are booming. Many manufacturers with "background" have entered this field one after another, such as Huawei, Meizu and Xiaomi, which are well-known in China. In 2014, all kinds of wearable devices came into being at the right moment. There are several kinds of wearable devices evaluated and disassembled by Aipan.com, such as Flashclip pedometer, Goodong bracelet and even Aismart bracelet. These devices have similar functions, principles and even looks.

This article is about entry-level, single-function wearables. Don't be confused with high-end wearables like Google Glass, Apple Watch, and Samsung smartwatch.

This kind of wearable device has several distinct features:

Low threshold of entry -- simple design scheme, mainly micro controller + low power communication scheme + sensor scheme

Microcontrollers are mainly low-power MCU, such as 32-bit Cortex-M3, M0, M0+ series, or more simple 8-bit microcontrollers

The communication scheme is mainly bluetooth 4.0 with low power consumption

Sensor suppliers are more well-known ADI, ST, BOSCH, Kionix and so on

After understanding the features of these entry-level wearable devices, we will first disassemble a Smart Band of Lianyai that we experienced last time, and then compare it with Flashclip pedometer and Gudong bracelet hardware solutions disassembled by Iband.com to enhance our understanding of wearable device solutions.

Perhaps in order to further ensure the waterproof function of IPX4, the main body of the bracelet "body" is bonded with glue, and the panel network engineer can only open the body through small destructive disassembly.
