WT32-ETH01 ESP32 Module Ethernet WiFi Bluetooth Development Board WT32-ETH01 Embedded Serial Port to Ethernet Converter Serial to WiFi&Bluetooth MCU Module Pack of 1

Same WT32-ETH01 you'll find anywhere else. Got it up and running on my wired network using the WebServer_WT32_ETH01 Arduino library and the same FTDI serial programmer I use for ESP8266 boards. Note that it comes with the header pins pre-soldered upward as shown, which isn't very breadboard friendly, so make sure that will work for your application.

This board will not work when using a power supply on 5v & Gnd. The red led will turn on but when connected via the io2 pin to data on led they will not power on. WiFi will not work either. If you attempt to flash it using the default pins the software will give an error regarding pin layout. Members on forums are all puzzled as to why it's not working.Second board I was sent didn't have any pins or any included in the packaging. Very disappointing experience so far.

At least 50% of the batch of 4 I got do not seem to be either printed incorrectly or have bad components. The 5v pin doesn’t seem to power the soc and the 3.3v pin doesn’t seem to provide enough power to operate the Ethernet port. Maybe they intend for you to supply 5v and 3.3v but I bought some from a different maker 6 months ago that appear the same and that’s not the case. Sure these are cheap and you get what you pay for but something is fundamentally wrong with this batch.

I have programmed many controllers over the years. I have all the correct drivers for this, the adapter, etc....... I simply will throw a connection error during programming attempts. The seller shows a USELESS video (Horrible) I bought this back in Dec 2022 but just recently wanted to use it.
