Summer outdoor power bank

This PCB design is based on the INJOINIC IP5306 battery management chip and utilizes four USB charging interfaces: Type-C, Micro-B, Mini-B, and Lightning-USB, increasing product

compatibility. External pads are also provided for use with microcontrollers and other peripherals. To facilitate this, the HeZoo Air001 chip is added to wake up the power chip during low-power operation. Four LEDs (red, orange, yellow-green, and green) are used to indicate battery
level .
The PCB design includes
BOOT and NRST test points for easy programming of the Air001 chip.
