The Huawei Ideos S7 is a commercially available tablet in the USA.
Overview
The Huawei Ideos S7 provides 256MB of memory and 8GB of eMMC storage
Note: The Huawei Ideos S7 Slim is a different design, which incorporates more battery and uses a projected capacitance touch screen.
Display
The display size is 7" diagonal w. 16:9 aspect ratio. The resolution is 800 x 480. A single point resistive touchscreen is integrated.
There are two internal speakers, independently wired, and an internal mono microphone.
Connectivity
The Ideos S7 has 3G, 802.11b/g WiFi and Bluetooth, using three individual antennas.
Location/Movement
The Ideos S7 has an accelerometer.
Ports
- One micro USB OTG (power output only)
- One multipin connector, use undefined (docking ?)
- One microSD card, externally accessible
- One DC input port
- One stereo Headphone Jack (3.5mm)
Power
The Ideos S7 has a 8.2Wh Li-Ion polymer battery (3.7V @ 2200mAh).
Breakdown
The tablet has a steel back plate which removes to allow access to the battery, SIM card, and manufacturing diagnostic ports. There is a larger plastic back cover which removes to allow access to the motherboard. Removing the back cover requires removal of six T-6 screws under the steel plate (hidden under plugs as well) and four T-6 screws in the front (hidden behind the flexible black plastic glued to each side of the display).
Electrically, the tablet consists of a motherboard, two auxiliary flexible PCBs (front facing camera, light sensor, and input buttons), the display and the touchscreen.
The motherboard mainly consists of a 45mm x 60mm processor module, which contains the SoC, DRAM, 3G, and Bluetooth circuitry. This is manufactured using a high density interconnect PCB w. tightly controlled impedance. The main motherboard provides additional peripherals and system connections. In the area of the motherboard underneath the display (most of it's area), there are no components mounted and most of the surface is plated in gold (the remainder has soldermask). This contacts a conductive mesh bonded to the steel frame around the display.
Height
The tablet thickness is roughly 15.8mm in the middle. The height stackup is:
| Touchscreen: 0.5mm | ||
| Cover Glass: 1.1mm | ||
| Air Gap: 1.7mm | ||
| Display: 5.9mm | ||
| Steel frame: 0.8mm | Battery: 5.9mm | |
| Motherboard: 4.5mm | Camera: 4.5mm | |
| Back plastic: 1mm | ||
| Steel Back Plate: 0.8mm | ||
Weight
The tablet weight is roughly 510 grams. This breaks down as:
| Cover Glass/Touchscreen/Bezel: | 130g |
| Display: | 152g |
| Motherboard: | 64g |
| Battery: | 52g |
| Back cover: | 106g |
| Total: | 504g |
