Snowflake lamp_charge/discharge base

Preface
First of all, I would like to thank the author of Snowflake Lamp, Mondraker, the original post address ->> Jump ->>>>.
This design draws on Aant’s design, original post address ->> Jump ->>>>.
There are flaws in this design. In order to reduce the brightness of the snowflake lamp, I changed the current limiting resistor of the LED from 20Ω to 200Ω. Using IP5305T/IP5306/FM5324GA, too small a current will cause the chip to enter an automatic sleep state. The original version of the snowflake lamp has not been tested yet. I will try it again when I have time. You can use the sleepless version IP5306-CK to solve the problem.
The button can control 5V output, turn on the machine alone, and shut down with a double click.
It adopts TYPE-C interface, adds charging identification resistor, and supports fast charging head. The blue light flashes when charging and stays on when fully charged. The blue light is always on when discharging, and the blue light flashes when the battery is low.
