I bought a Uno board, an arduino nano and an esp32 s2 mini from temu at comparatively cheap prices.
The uno seemed to be working fine, but the nano and esp32 board isn't detected by my laptop properly even though the drivers are installed. I tried switching cables several times but it doesn't work. My chat gpt and I have concluded that the boards must be innately faulty.
Has anybody experienced similar things from products from Temu?
I trusted Temu because my UNO board seems to be working, but after confirming that nano and esp32 don't work, I gotta shed a new light on my UNO boards supposed inability to circuit my smart watering project properly...
Can you expand on this? Is there any indication that the boards have been detected by the OS? Does your Device Manager (assuming a WINxx based PC) show any additional devices when you connect the Nano or ESP32?
I have had good luck with them but I am using Linux which does not appear to have the driver problems windoz has. You can try a different computer and see if that helps. If it is blinking something on the board is working.
The nano board blinks and the pwr LED turns on when I connect it to my laptop, which is not a bad sign. I have a debian run single-board computer made from ASUS which isn't a temu product, and tried connecting both boards to that, but they don't seem to work on that as well.
When the nano board was primarily connected to my laptop which is windows, it changed absolutely nothing to the device manager. There was no ports(COM) appearing(there were none in the first place) and no additional devices showing up. Only the PWR LED on the board lights up and L LED blinks.
So I followed through a set of instructions that my GPT advised me, which would allow me to essentially download the CH340 driver from the offical WCH website, check for any conflicting drivers, install the driver as administrator, disabling the dirver signature enforcement and manually reinstalling the driver. It turned out that the CH340 driver was already pre-installed on my PC so there definitely is a problem if it wasn't detected in the first place, and I checked the label on the chip of my nano board and it definitely said WCH which means its not an FTDI driver that I am looking for but an WCH CH340 one. So none of these worked.
It's okay!
sorry! I got tangled! missplaced diodes should be missplaced components.
I will send you an image an mapping of a Arduino nano esp32! Arduino Nano ESP32 Pinout.pdf (1.9 MB)
Thank you for your kind attachment of a nano board layout. Here I attach what my nano board looks like. I think it is different from what you have shown me.

yes.
my example is a nano esp32.
But in my opinion, this nano board is fake.
The Arduino nano must have the Arduino logo to show it's real.
From my experience, The Fake Arduino boards have a low quality of conection and has a lot of errors. so I Recommend buying a Arduino Nano from another company or from the real Arduino store.
Also to elaborate on the status of my ESP32, the S2 mini board shows up on the additional devices tab when I connect it to my laptop and click the reset and the other buttons together, with a yellow exclamation mark sign. I tried downloading the drivers for the board, but it doesn't work. To my memory, I think the error message was that the driver was already there. Let me get back to you after trying it out again.
Finally here is a picture of the driver when the ESP32 is connected. You can see the connection detected on the additional devices with an error. I tried downloading the drivers on the properties tab, but either it couldn't find the driver even though I set the path to the downloaded driver install programme location, or they couldn't find the driver download from the internet or wherever.
