Lithium battery power display module (four segments)

Overview

This project is a function that I temporarily thought of adding when designing a Bluetooth dual-mode mechanical keyboard. In fact, it doesn't make sense to just look at this board, but you can refer to it and integrate it into your other designs. I'm a pure novice, so I'm asking the boss to give me some light spray. This design shares the design of a CN1185 lithium battery power detector with a maximum single-cell battery capacity of 1050mAh 3.7V. The maximum battery voltage cannot exceed 9V during use. This project is ultimately integrated into the main control of a Bluetooth dual-mode mechanical keyboard as a power display. With reverse polarity protection. Can be used as a reference design for DIY.

A small white circle appears on the AD16 PCB
When I was generating the PCB, these small circles, white lines, and thin lines appeared, each with "<0mil" marked on it. How should I solve this problem?
Why do smart water meters use disposable 17450 (or other models) disposable lithium batteries? Why not use rechargeable batteries?
Why do smart water meters use disposable 17450 (or other models) lithium batteries? Why not use rechargeable lithium batteries? Is it because of price or some other factor?

How do Wi-Fi antennas work? How do you test and evaluate the performance of Wi-Fi networks? (Part 2)
In the digital world, both personal and business environments cannot do without the Internet. Computers, smartphones, and printers all need to connect to the network for communication, and Wi-Fi wirel
A little experience in getting started with MSP430 programming
I first came into contact with MSP430 at this time last year. At that time, I needed it for an internship outside. The first time I came into contact with MSP430F149, a relatively classic chip in MSP4
