In the territory of smart hardware, smart watches is not new. Samsung Sony's smart watches have done the second generation, but life, application scenarios, industrial design, etc., so that they have always had topics but there is no big sale. This year, MOTO 360 and Apple Watch are more hot in the topic of smart watches. The smart watch is actually different, and it is mainly similar to the auxiliary screen of the mobile phone, or increases the motion detection function. This year, Ewistech also dismantled the smart watch in various markets around the world, which can be used to see the difference between the works on the scheme with their Eseeker.
Samsung Gear Fit
Gear fit should not be a smart watch, but it should be a health monitoring and exercise tracking smart bracelet, but it has an AMOLED display that can act as a mobile phone auxiliary screen, display phone, short message, etc. The general sports bracelet function is richer.
Gear Fit takes the wrist strap and body separation design, directly removes the main body module from the strap. All disassembly is not complex, and the front and rear plastic shells, a display, board and a battery. Supports IP67 level waterproof, but the dismantling is not difficult.
On board, the main IC of the Gear Fit motherboard: Texas Instrument TUSB1211, USB 2.0 high-speed ULPI transceiver, MELFAS MMS-136 touch chip, heart rate sensor temporarily unrecognizable model number and manufacturer information, Meixin Company MAX77836EWZ micro USB controller and Lithium battery charging controller, and Ruijing semiconductor RT8016, antihypertensive DC-DC converter.
The main IC of the circuit motherboard: Should Masheng MPU-6500, six-axis gyroscope and accelerometer combination chip, Wang Hong electronic MX69V28F64 16MB flash memory, integration Semiconductor STM32F439ZI, ARM Cortex-M4 single chip, Toshiba TC358740XBG, Camera Bridge, Boyong BCM4334, Wi-Fi, Bluetooth 4.0 and FM combination chips.
Galaxy Gear
Samsung's first smart watch, this watch supports voice calls, viewing information, step, and a 1.8 million camera on the strap, support autofocus independent taking pictures. The construct is slightly more complicated, and the deck is divided into four parts, the metal buckle is two parts and two types of straps, one of which is also integrated with a video-like window; camera module, speaker module, display mode Group, board, battery, and housing.
On the motherboard, IC is mainly concentrated on one side, Samsung ARM Cortex-A9 hunter 4212 processor; intention to semiconductor STM32F401CB, 32-bit ARM Cortex-M4 single-chip microcomputer; use Korean local MELFAS MCS-8000 touch IC; blog, bcm20702 Bluetooth chip; Yamaha Ymu831 audio codec chip; Samsung's S5M8767 power management IC; Hexa-axis gyroscope and accelerometer combination chip should be combined with Masheng MPU-6500.
Sony SmartWatch 2
Sony SmartWatch 2, there are two types of metal and plastic straps, with metal straps are also a large feature of SmartWatch 2, and the dismantling of the metal strap and the metal surface of ordinary watches are consistent, which can be broken down into two types of straps. A buckle and four ears (small steel rods of fixed straps), the main components other than the straps include screens, motherboards, batteries, NFC modules.
SMARTWATCH2 motherboard aspect: Austrian microelectronics AS3677 backlight drive, Semiconductor STM32F429 ARM 32-BIT CORTEX-M4 microprocessor and Magic Technology P-SRAM, Bosch BMA250 triaxial MEMS accelerometer and Astronity into ak8963 three-axis electronic compass.
SMARTWATCH2 motherboard: Toshiba THGBM5G5A1JBAIT 4GB flash memory, Texas Instrument TPS657202 power management chip, STMS STLC2690 Bluetooth / FM chip, SmartWatch2 battery is directly welded on the circuit board.
LG g Watch
Samsung, Sony and other manufacturers have sent smart watches, and LG is not idle, and the first batch of smart watch G Watch, which is the first batch of Android Wear, supports all Android 4.3 and above. The G Watch structure tends to modular, and the entire table is divided into three parts of the body and two tables, and the body is made of screen modules, lithium polymer batteries, motherboards and rear shells. Since the watch supports waterproof, the rear shell and the middle frame are arranged in a ring rubber ring.
LG G Watch circuit motherboard aspect: Sea Kexi H9TU32A4GDMC 512MB running memory and 4GB flash memory, high pass APQ8026 quad-core Cortex A7 application processor, integrating semiconductor Lis3DH three-axis accelerometer.
Should be a Japanese inMP441 six-axis gyroscope and accelerometer combination chip, and high-pass PM8826 power management chip.
LG G Watch circuit motherboard, another side: Synaptics S3402B touch chip, Bo Tong BCM207 Bluetooth 4.0 chip, Yimegis ISA1000 haptic drive and AKM AK8963 three-axis electronic compass.
Moto 360
MOTO360 should be a market focus rate only to an smart watch in Apple Watch, which is also equipped with the Android WEAR operating system. The design of its circular dial is favored by many people. From the disassembled part set map, it can be seen that in order to achieve a circular dial, many modules make a corresponding compromise, round screen, round motherboard, and the like.
One side of the MOTO 360 motherboard: Temple digital signal processor with Texas Instruments, equipped with Texas Instrument OMAP3630 ARM CORTEX-A8 application processor, Magic MT46H128M32L2KQ 512MB running memory, Texas Instrument TPS659120 power management chip, Eitme MXT112S touch chip , Toshiba THGBMAG5A1JBAIT 4GB flash memory, Texas Instrument AFE4490 monitors the analog front end of heart rate pulse.
The main 6 ICs of the motherboard were from Texas Instruments.
Should be a beautiful MPU-6515M six-axis gyroscope and accelerometer, as well as fewer dual-vibrators (larger intensity).
From the above five smart watches, the current smart watch is based on the main IC combination scheme for microprocessor (or single chip) + power solution (battery + power management chip) + communication + sensor. The microprocessor or single-chip is responsible for the calculation and management of the equipment, the battery, and the power management chip are responsible for the power supply of the entire device. The communication scheme uses NFC, Bluetooth, and the sensor selects acceleration, gyroscope, compass, and heart rate monitoring according to functional requirements. Can a watch is more complex, power management, and the use of the sensor and most smartphones are quite.
At present, the intelligent wear equipment market is moving upwards, from the three-star a year, 5 smart watches can be seen in the intelligent watch, from only the self-portions of the Galaxy series Mobile phone to compatibility with most Android (equipment for Android 4.3 and above), you can also see that Samsung's product layout of smart watches is made to the mass development market. At present, Samsung, Sony, LG, Motorola, Inwatch, Hi-Peel has released smart watches, but the smart watch is still not warm, and it is still the smart watch on the market in the current market. And the functional experience has not changed, and there is no more unexpected surprises, and has been in the user experience with good reputation Apple. As early as 2013, the news said that Apple was developing smart watch. At the Apple new appling in September this year, Apple Watch was released, and the time to market is more likely to wait until the middle of March 2015 - at the end of June, when it is the apple of the mobile phone boundary, what will be brought us? Experience, worth looking forward to.
