I was totally unaware of WCH (China mainland) IC chip manufacturer up to date.
I was looking to follow a recommendation from a Chinese manufacturer, as he insisted / recommended the use of CH340 based USB to TTL converter.
At the year 2025, latest work of WCH this is the upgraded CH343G.
The latest supports any known protocol, bandwidth this is now at 6Mbps instead of 2Mbps = CH340
CH343G this is development of 2023, it comes with driver support starting for Windows XP up to Windows 11
It hidden advantage, it works trouble FREE even if USB input voltage this fluctuates from 4.0V up to 5.5 Volt when a PC motherboard USB port and or a USB HUB, this is used as a power source.
This advantage serves best any electronic device that requires DC power input along a TTL connection simultaneously.
According to USB standards, any USB port this deliver up to 500mA continues.
This New WCH IC, this now working down to 4.0V, while the older CH340 it could work from 4.5V and higher.
In conclusion, The purchase of CH343G based product this makes sense at 2025, it can serve at home and industrial applications, it supports all known operating systems.
It support TTL voltages 5V, 3.3V or even 2.5V, 1.8V.
Best solution for electronics that require DC power and Data communication simultaneously.
CH343G IC power consumption this is at 1/10 from other competitors (ECO Friendly power management).
