true holes rs232 to USB chip?

[Yves]

Hello all,

Is anyone knows if a simple RS232 to USB though holes chip exist?
I get my boards made by firms but I'm still do hold fashion through holes designs when ever possible. I find difficult to solder those small pins. . Thank you

Yves

Hi,
Why don't you use a module like this.  https://www.ebay.co.uk/itm/294651016995?chn=ps&_trkparms=ispr%3D1&amdata=enc%3A1UidB-9jxS6uxTZAmlnethw92&norover=1&mkevt=1&mkrid=710-134428-41853-0&mkcid=2&itemid=294651016995&targetid=1647205088800&device=c&mktype=pla&googleloc=1006907&poi=&campaignid=17819795917&mkgroupid=137883623263&rlsatarget=pla-1647205088800&abcId=9301024&merchantid=113716259&gclid=Cj0KCQjwguGYBhDRARIsAHgRm49tZcjrss4u_uu-gyuOGuOScPV69Cmrghfl6aHicugBeuNrB45w8WAaAubrEALw_wcB

The simplest chip is CH340C, it doesn't need other components to work, the format is SOP16

I have this chip it is very small and using very few components CH330N is to include it in a PCB board it works very well, I hope it works for you friend, greetings

NOTE: the voltage can be connected to 5V and the TX and RX output levels are TTL
If you want to use it as rs232 use a MAX232

I recommend the CH340G UART module, it is already assembled, and it works very well with WINXP up to WIN10, it is very stable, I have never had a problem with disconnections, it works very well for any communication with any chip

Many thanks to all for the information. It looks for me I should opt for a breakout module to connect to the existing board. Those breakout converter are relatively cheap and easy to implement.  Many thanks again.
