OK tested latest IDE 1.8.19 /Win7/64 bits for UNO R3 /CH340 chip but only after separate CH340 driver additional install!

Development Tools IDE 1.x

My recent IDE setup experience to share if useful...

I have recently started with Arduino while intending to a large automation engineering my new full green house, factually to optimize solar panels energy capturing and much more around.

So, I bought a simple basic Arduino UNO R3 /328p board from locals just for some first tests to control some power relays with various senzors and logical structures intending to buy a real one soon from its origin here!

By this occassion, even if lower expected (due to my old favourite OS Win7) but very happily... I have recently tested as very OK, the latest IDE 1.8.19 on my Windows 7 /64 bits for UNO R3 with CH340 chip to program scripts and then send and run them from my DELL laptop.

I simply plugged in USB port for both supply and control my new R3 CH340 !

ATTENTION! Original setup file for new 1.8.19 downloaded from arduino.cc does not properly install USB/COM serial drivers even if it claims it, for this notorious CH340 chipset board at least!
In fact I found no alike information concerning with which chipset type they use in the board they sale...???
So, webmaster should add this critical specification in order to avoid our loosing time to research how fix their unmatching setup files blindly downloaded from origin site!

Anyway, after a lot time lost research within various forums etc I have just succeeded to fix marvelously simply by found THIS LINK ! to get a real CH340 driver then to setup and all now works finelly !

Notice: after download and unzip, do not forget to change to compact successive folders you find and renamed it any you want but short lenght folder name in order to fix potentially driver setup error (because of that older times embedded installer that not find long strings folder names!)
Procedure above needs no uninstall, just run it even after driver failed normal IDE installation no matter its included other drivers!

New IDE 1.8.19 works like a charm now, fluency fast within new very well done compact and functional interface even if I will allways prefer older Windows 7 /64bits instead of all newer for a lot of critical things that experimented ITs already knows about...

Now, happy to donate and buy some more ! :sunglasses:

Your claim is a little off the mark. because the original Arduino Uno does not need the CH340 driver - there is no such chip. If you bought a board with CH340, then it is a clone and the Arduino company cannot be responsible for its operation.

But in principle, the fact that the CH340 needs a separate driver installation is written on many sites and I don’t quite understand why you spent so much time on this

I have bought it officially from one of best high tech IT store in Romania that is plenty of very advanced devices and micro boards that in really means are not quitely found anywhere today or there are out of stock out of manuals documentaries etc
And the issue related with that CH340 is same as I said but you maybe not check deeply all the sites as me when searching for a VALID download release to reliably recover it!
Yes you are right as also me found many sites and forums talking about but today most of them have no more valid links to those drivers to really enable reliable control from USB laptop especially when use Windows 7 as I will always prefere for much advanced IT reasons
You will realize if check the links deeply and then loose time enough to find one really downloaded and then able to finalize somehow no simple installation especially on windows 7 which si much better for many other things simultaneously on same laptop (I use it for marvelous other apps intensive on my Intel 7 64 bits; If upgraded to Window11 I were loosing more than half useful processing power required by my other much intensive apps like Ableton Full, Fruity Loops Full, timeshifting, DJI control etc etc)

Another trouble I met with unreliable uncontrolable tone() uncontrolled by syntax feature same as many others all around the world claimed but probably as you told, because of same cloning maybe of your great board.

Anyway I waited a little to clarify your new boards as I intended to buy from you next step I mean UNO 4 but I still concern with its annoying lower level output current that now is no more directly capable to lead my power relays that my current clone UNO 3 one...

So your great development seems to be leaded to another focus than maybe more users like me with larger expectations from upgrading!
So I am very sorry to find that upgrading to higher processing power and memory like buy UNO 4 to replace my clone UNO 3 could become more risky and complicated for my solution design higher wishes...
I use Arduino to control power consummers around my experimental new residence while depending by clouds shadow and battery status and history etc
As Arduino is today very smart and compact to lead my power relays and also directly some buzzers alerts I do not intend to complicate this diagram with new intermediate interfaces to avoid burn risks for its too sensitive output for as a price for better processing...
On the other matter I do not like enhance unhealthy EMF smog due to WiFi etc radio interface that exclusively comes with your new and best UNO R4 (R4 minima has a lot disvantages in relative with R4 full that comes with WiFi included).

Regards and waiting for a more attractive internally structured upgrade as you really can !!!
(best to buy is an UNO R4/5? with powerful outputs (>0.1A to directly supply usual 220V/30A relays) and WiFi etc only as external plugin , all the rest internally at your best UNO4 more memory faster processing, more simultaneous Analogue Inputs readings and so on, of course at an affordable price. Anyway I prefere to pay 3 times more meaninig around 60 euros for all of these instead only 18-24 euros for a somehow poor upgrade for me as the new UNO4 listed this moment)

Anyway now I am very satisfied globally of what Arduino can and not my fault that taken in seriously local offer that I bought and really runs all at best with those 2 exceptions above...
