[CH246 & CH241 Wireless Charging Kit Evaluation] Part 1 - Getting familiar with the evaluation kit [Copy link]

The wireless charging kit from Qinheng was delivered to me by express delivery and included a transmitter board and a receiver board. Each board had a coil.

The transmitting coil is a wireless charging coil with an isolation magnetic sheet. After a careful inspection, I found that the magnetic sheet was broken during express delivery and a piece was missing. I checked online and found that if the isolation magnetic sheet is damaged, the efficiency will be reduced because magnetic lines will leak out from the broken part.

The receiving plate coil is a hollow self-adhesive coil.

The main components on the board:

There is only one dot indicating pin 1 on the surface of the transmitter controller IC on the transmitter board, and no other mark information. This is a bit strange.

The IC mark of the receiving controller on the receiving board is 241, indicating that the device is CH241.

There is only one dot indicating pin 1 on the IC surface, and no other marking information. It is really strange.

Still polishing it?
