Recently, Ewistech did a lot of children's version of intelligent wear. We also found a lot of bright spots, including the increase in the function of children's watches and applications, and the requirements for the integration, lightness and power consumption capacity required for the watch processor are also gradually increased.
eWiseTech recently released shortly before the dismantling of the little genius little genius Q1A children watch phone. What is the characteristic of its processor?
The small genius Q1A childcare phone watch has a total of barefruit and bamboo. Suitable for boys and girls.
This weight is about 51G watch (including the table), equipped with HD video calls, 7 days long standby, AI precision positioning, 4G two-way call, IPX8 intelligent waterproof, real-time microcamline functions.
Dismantlement step
After the value is appreciated, it is necessary to start EWISETECH engineers to dismantle the small genius Q1a children's telephone watches. Xiao e dismantled the red pomelo.
First take the table, since it is a child watch, the TPU strap is selected and the lock screw is fixed. The strap is better, and the breathable effect is better.
The SIM card on the back needs to be opened through the pickup device given by the attachment. There is a waterproof rubber ring around the card cover, and a graphite film is placed at the SIM card.
The outside of the watch did not see the screw, the engineer found that the screen module and the rear cover were fixed by the adhesive. So insert the slit between the screen module and the rear cover. After removing the back cover was found, which is a circle waterproof foam.
The speaker is fixed to the back cover by gum and is connected to the motherboard through a transfer soft plate, and the speaker is waterproof by waterproof film. On the other side, a waterproof label is attached to the charging contact position, and 2 magnets are attached to the adsorption of the charging base.
The small genius Q1A children's phone watches use ATL's 700mAH lithium polymer battery, and the battery voltage is 3.85V. This battery is pasted on the motherboard by adhesive, and the motherboard is fixed by the screw.
The motherboard and the battery are fixed by a foam glue, conductive tape and white solid adhesive.
After the camera is fixed with a white plastic sheet, the screen and the case are separated by heating through the heating station. Circle around the screen affixed with foam rubber, waterproof can play a role. The watch antenna is integrated on the case.
Motherboard
The SIM card slot of the motherboard has a waterproof label. The lateral microphone position also has a microphone waterproof film.
There is a radiating copper foil on the other side of the shield, and a heat conductive silicone is attached at the processor and the front end module chip position.
The main processor in the watch, Q1A is equipped with a purple light exhibition Rui W317 processor, integrated 2G / 3G / 4G, BT, Wi-Fi, GNSS, PCB layout flexible, can be made of single-sided plate; built-in MODEM the field test more than 200 operators worldwide, providing network services to more than 90% of the population worldwide. Also precisely because of the AI eight-positioning technology of Violet Exhibition W317, high-precision positioning SDK software package, the small genius Q1A has super-AI precision positioning.
After further analyzing it, the engineer found four DIE, including the Violet Exhibition W317 processor, integrated with LPDDR and NAND in the Violet Exhibition Rui UWS6131 chipset.
Look at it specific location on the motherboard.
The main IC of the motherboard (below):
1: UNISOC-UWS6131-Violet Exhibition Rui W317 processor group
2: Spreadtrum-SC2721G-Power Management Chip
3: Spreadtrum-SR3595D-radio frequency transceiver chip
4: Rui Shi Cixing - RR88916-81-Front End Module Chip
5: Lou Electronics - Microphone
The main IC on the back of the motherboard (below):
1: Ruite creative core - RR88643-21-Front end module chip
2: Semiconductor - Lis2DS? - Accelerometer
Summarize
Little genius Q1A children watch phone disassembly is relatively simple. 51g-weight and it is destined to internal and no extra member. However, due to its waterproof performance, waterproof treatment is visible in the interior, and some shockproof measures are visible. Big flaps on the motherboard also uses the heating of the whole piece of heat.
The selected purple exhibition Rui W317 processor is also designed based on a mature Mocor RTOS lightweight system, ultra-low power consumption architecture, and power consumption is optimized by more than 20%.
Also because the AI eight-positioning technology of the violet exhibition Rui W317, the small genius Q1A supports GPS, Beidou, Wi-Fi localization, base station positioning, camera assist, acceleration, A-GPS, indoor positioning, etc., combined with AI algorithm, Q1a The more accurate positioning can be used.
Violet also want to see the other exhibition sharp IC? Come to EwiseTech searched, there are also in these devices!
