ciy68 changed to lithium battery

Overview

It consists of a classic battery protection chip dw01, a classic charging module tp4056 and a voltage regulator chip lm3670. lm3670 is an ultra-low voltage step-down chip with a maximum discharge current of 350mA, and has features such as standby power consumption of only 15uA and simple peripheral circuits. This module helps you get rid of dry battery anxiety. As long as you install this module, you don’t need to buy dry batteries! It can be recharged when it runs out of power, but only for appliances that use two dry batteries connected in series. (Dry battery merchants cried to death QAQ)

How do you determine whether the code you write is synthesizable?
To sum it up in a simple sentence: Computers are never as smart as you. Specifically, EDA software is usually worse than humans in synthesizing HDL codes. For a piece of code, if you can't imagine a m
