01. [CH246 & CH241 Wireless Charging Kit Review] Unboxing [Copy link]

I won a wireless charger as a prize at eeworld before. Recently, there is a wireless charger evaluation activity. Now I apply to modify my Bluetooth headset compartment and smart watch charging station. I just received the express and made an unboxing post.

Here is everything:

1. CH241 wireless receiving module;

2. CH246 wireless transmitter module;

3. CH241 chip * 5. I didn't apply for any chips at first, but later I thought I might need to make a sample board, so I asked the administrator to apply for 5 more chips. Thank you for your hard work .

4. CH246 chip*1.

CH241 wireless receiving module (left); CH246 wireless transmitting module (right).

Verify the function of the chip: Since I don't have a multimeter to test at home, I'll do a simple test here and power the development board directly. Use a power bank to power the CH246 wireless transmitter module through type-C, and the indicator light will light up. Place the coil of the CH241 wireless receiver module in the middle of the transmitter module coil, and connect the output of the CH241 receiver module between the +5V and GND of the development board to power the development board. You can see that the development board is working properly. This shows that the system can work properly.

Next are the two products that will be modified this time (Meizu Bluetooth headset charging case and Meizu smart watch charging stand):

Meizu Bluetooth Earphone Charging Case: The CH241 wireless receiving module seems to be able to be placed inside the earphone case . The earphone case has been disassembled before, and it should not be difficult to modify. If this can be modified successfully, the watch charging stand can only be left unmodified for the time being.

Meizu smart watch charging stand: This charging stand is difficult to disassemble and has not been disassembled yet. In addition, the shape of the charging stand is quite special and there is a hole in the middle, which makes it difficult to modify. This product is an alternative solution. If the modification of the previous Bluetooth headset charging compartment is unsuccessful, then switch to this one for modification (if you want to modify this, the coil is not easy to hide inside the charging stand).

The next step is expected to be to buy a soldering iron and resistors and capacitors, as well as draw schematics and PCBs (the module board layout may need to be made smaller and the shape may need to be adjusted).

Now it's opened. Let me show you what the inside of this charging station looks like.

I'll post a teardown tomorrow.

Awesome

Disassemble it and put it back together?

Can be put back

I have installed it two or three times.

That's good. I remember some of them were stuck with adhesive tape, and it is often difficult to restore them.

I don't have glue on this one, it's a snap-on structure
