Hello there. I wann buy more esp32, but not sure how to find some good brands, or is everything just a lottery anyway? Many people complaining about different stuff, like bad wlan reception. Cannot test it myself, cause I got no wlan really. Or others complain, they don't have PSRAM as advertise…

I have a few of them and no problems. I do see others having problems, but we can normally get them working once they know how.

It's easy enough to find out, goto the github page and look at the open issues.

Are you looking for a german source for original espressif boards? conrad.de Not the cheapest, but reliable. I got my board of them and it´s slightly better quality compared to other ESP boards, which I tested. Specially better documentation at espressif.

[image] sonofcy: It's easy enough to find out, goto the github page and look at the open issues. There is NOT ANY sticker/link/extra info on it. Just 3 bare bags. :rofl: But I found it: GitHub - vcc-gnd/YD-ESP32-S3: YD-ESP32-S3 Micropython VCC-GND Studio This is the github for all N18R8 a…

The three bare bags may be a clue. I can't really follow all your complaints. I am not even sure what you want anymore. If you are looking for your serial log to be shown elsewhere, look at the following #include <WiFi.h> #include <PubSubClient.h> #include <MqttLogger.h> #include "wifi_secrets.h" …

[image] sonofcy: I am not even sure what you want anymore. Well I simply wanted to buy more esp32-s3-N16R8. since I have NOT tested all functionality(wlan) and someone on Amazon mentioned that it is a "common known issue" I asked for brands and stuff. But there seems to be only one for N18R…

There are a few things you need to learn. First, what a 'paid for negative comment' is, or a schill. Also, that ALL the boards are made in Asia, in one factory usually. Some companies buy the full dev board and label it, some buy just the SOC and build their own dev board. If you are sensitive to th…

[image] quantummagic: Cannot test it myself, cause I got no wlan really. Wlan means wi-fi here... If you don't have in your house, which sounds weird nowadays, you can always make a hotspot with your phone. Except if you don't use smartphone neither...

[image] kmin: Except if you don't use smartphone neither.. I used a hacked Samsung Galaxy S4 Mini GT-I9195 with customrom and bootloader untill now, 4G via usb tethering to pc. So slow, that testing with it would be useless, cause I could not tell who's fault it would be. I just received my…

A few of us were able to find the documentation on the Espressif site re the two USB ports without using AI. I will try to find the thread and post a link for your edification. Most of the helpers do NOT like AI as it is unreliable (I have tested it) and teaches people bad habits.
