Lubancat 0W UPS Power Supply

Preface:
During the development of the animal-themed movable eye system, I used the Luban Cat 0W. However, the Cat 0W's USB-C port was on the side, making it too small to fit, and there wasn't a suitable boost power supply module (dragging a power bank along would be too abstract).
Therefore, I created this integrated power supply module, which combines charging and discharging. I initially considered buying a ready-made UPS board
from Taobao
, but the price was 128 RMB and only available in Raspberry Pi-sized versions, which was prohibitive. So, I created my own
reference design using a similar approach. It uses spring-loaded pins to connect the power supply pins at the GPIO and the I2C interface to the Cat 0W.
Modifying the board size allows for compatibility with the OrangePi Zero2W and Raspi Zero2 2W series, as well as other similarly sized development boards
(for the Raspi Zero2 2W, see another dedicated project that integrates a docking station, power supply, and eMMC module).
The current discharge status can be read via the connected I2C interface (please purchase the IP5310-I2C version).
Library files and register manuals are also included. Thanks to the link to the attachment from the user "youli".
