Yingjixin IP6826 wireless charger

IP6826 wireless charger version 5.0, this project is the first project of this open source platform. It was diverted, and when it was made private and modified, it was used by others to design and open source. Actual measurement of QC power supply charging iPhone 12 can pop up the charging animation. When the coil is accurately aligned, the maximum power is 9W. This is basically the limit of
third-party wireless charger for iPhone. Huawei, Samsung and others can trigger fast charging. This chip is relatively unique. For chips
with fewer peripheral circuits and higher power, they are very suitable for development. Note:
Remember not to solder the chip in the opposite direction! ! ! I will cry if I continue! ! !
The pins cannot be connected with tin, and the QFN package is not friendly to novices. You need to use a soldering station to solder, and of course you have to use a soldering iron.
The temperature should not be too high when soldering the chip. If soldering, you can use a soldering iron to hold it up. The TYPE-C must be firmly fixed! ! !
The 10uh in the BOM table is the coil. Be sure not to buy the 10uh inductor! ! ! ! !
R9 is an NTC thermistor! ! ! ! !

2835 chip LED lamp bead
The LED on the board is 2835 package It’s because I happen to have this packaged LED on hand. It has many colors and is very
beautiful! ! ! If you have LEDs in other packages, you can change the package if you don’t want to buy new ones. Video demonstration at Station B: https://b23.tv/VaZ7tFe (same name as Station B)
Warm reminder: If the light does not come on after welding, first check whether the positioning mark of the chip is in the same direction as the mark on the board
. If there is no problem, continue Check whether the LED is attached backwards. If not, please check whether the TYPE-C is connected to the tin and
whether there is voltage. If it still doesn't work, consider the problem with the charging cable. There is nothing wrong with the board. It
has been tested.
You can open this project through "Open in Editor" above. Recommended version 3.0 of the board! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! All capacitors must be 25V or above! ! ! This project has been being improved. It is currently the final version and will no longer be perfected. If there are any problems with the previous reprinting test, please proof again based on the final version. If there are any problems, you can give feedback in time and we will change it as soon as possible! ! ! ! QQ: 3587968576
