[CH246 & CH241 Wireless Charging Kit] Unboxing and Hardware Appreciation [Copy link]

Thanks to EEWorld and Qinheng for their support, I got the chance to review the CH246 & CH241 wireless charging kit. Thank you very much! I can finally make my own wireless charging appliance.

In fact, I got this kit in mid-to-late January, but it was abandoned at that time. Then I had the Chinese New Year holiday and only officially started working on it today.

1. Packaging

The anti-static plastic bag packaging is very simple and compared with MPS, it is so down-to-earth.

After unpacking, there is a charging kit, which is the sending module, and a power receiving kit, which is the receiving module.

2. Sending module

The wireless transmission kit is as follows

The schematic diagram is as follows:

Features are as follows

When the sending module is powered on, two lights will light up

After 2-3 seconds, the LED goes out.

After the wireless receiving module receives the signal, the blue light turns on.

The standby mode is off. One side of the wireless coil is anti-magnetic. The wireless charging needs to be placed on the coil side.

3. Receiving Module

The interface module looks like this after unpacking.

The schematic diagram is as follows

Features are as follows

The size is also relatively small

This is the end of the unboxing part, and the DIY evaluation will be carried out later.

I should give you some chips for DIY design, so you can try to draw them yourself.

Qinheng has applied for 2+8 separate chips. It is really awesome and deserves a thumbs up!

Does the wireless charger provide a square wave signal when it is working? What is the frequency range?
