Miwu Technology is one of Xiaomi's eco-chain enterprises, focusing on PC peripherals and efficiency tools. It is aimed at the charging needs and scenarios when playing games in the office. Prior to this, Miwu launched its first wireless charging mouse pad and Miwu smart mouse pad on Xiaomi Youpin platform, and we deeply disassembled them. Recently, Miwu launched the second mouse pad supporting wireless charging: Miwu wireless mouse pad. It's the first time for us to get this product, and the next thing to bring to you is the unpacking and dismantling of this product.

First, take apart the wireless charging mouse pad of Mi.

Product Chinese name: rice wireless charging mouse pad. English name: MIIIW wireless charging mouse pad.

The product is packaged in an envelope, and the back is the main specification parameters of the product.

Product selling points include: multiple charging protection, support for Qi wireless charging, luxury and elegance, and ultra-thin design.

Product model: mwcp01; Product size: 300 * 210 * 4.9mm; Manufacturer: Beijing Miwu Technology Co., Ltd.

Envelope packaging design.

Tear it open.

Package: wireless rechargeable mouse pad and instruction manual. There is no charger and data cable attached, which may be due to the consideration of reducing product cost and selling price.

These two kinds of accessories are not necessary for most people in the era of surplus electronic products, because one set can be seen everywhere at home, and it is easy to buy even if it is not available. It can be said that there is no collateral and it does not affect.

The product is black, rectangular and rounded.

There is a rice logo in the lower left corner: miiiw.

The surface is made of leather-like PU material, which highlights the appearance temperament and style of the product. At the same time, it provides good skin-friendly feeling, wear resistance and corrosion resistance.

On the right side of the mouse pad is the wireless charging area.

The ring gear-shaped imprint indicates the position where wireless charging needs to be aligned, that is, the position of the wireless charging coil below.

The lower shell of the mouse pad is made of all-aluminum alloy, which ensures the overall structural strength of the hard mouse pad. At the same time, the surface is treated by wire drawing process, and the value is good.

Soft rubber anti-slip pads are installed at the four corners to prevent the mouse pad from sliding during use.

The charging interface type is the common Micro USB.

Connect QC fast charging charger and charging cable to supply power to it.

After power on, the LED indicator near the interface lights up.

Then look at the size of the product. The product adopts light and thin design, which is easy to carry around.

In terms of size, it is larger than iPad Pro 1 1 inch.

Thickness is thinner than iPad Pro 1 1 inch.

You can charge the phone wirelessly when you wear it.

On the left is the mouse activity area.

The renderings in daily use.

ChargerLAB POWER-Z KT00 1 Portable Tester is used to monitor the input terminal, and the wireless charging aging test fixture shows that the product supports wireless charging modes such as 5W/7.5W/10W..

Second, remove the mouse pad and charge the rice wirelessly.

Use a crowbar to separate the mouse pad.

It is divided into two parts: aluminum base and mouse pad.

The mouse pad is hollowed out above the wireless charging part to reduce the thickness and maintain consistency.

The wireless charging board and coil are attached to the aluminum alloy bottom plate.

Compared with 1 yuan.

The back of the magnetic separator is insulated with high-temperature adhesive tape, the capacitor position of PCB is hollowed out to reduce the thickness, and there are no components on the back.

In the wireless charging part, the circuit board is relatively simple.

Third, the charging head net disassembly summary

The creative combination of mouse pad and wireless charging board makes full use of limited desktop space, and Qi wireless charging technology makes it easier to charge debris time.

The wireless mouse pad is well designed, and the internal hollowing design reduces the thickness, making the product a whole. Wireless charging adopts the scheme of GD single chip microcomputer plus SCT core-continent integrated power stage, which has high integration and reduces the area of circuit board.
