I don't think there's a D1-ESP32 board? The D1 Mini is Wemos' ESP8266 board. They do have ESP32 boards with the same footprint, but those are not D1 Mini but S2 Mini, S3 Mini and C3 Mini, depending on whether it's ESP32-S2/-S3/-C3.

You'll find many varieties of boards with different SoCs being sold mentioning the D1 Mini in their model number or product description, as it initially defined the form-factor being referred to. Similar to the ESP-12F, which you can also get with ESP32 SoCs, if you want, even though the ESP-12F originally is an ESP8266 board.

That's what I thought as well, it is not available at:

But the specific board from the post can be bought on Amazon:

Indeed, there is no D1-ESP32 from Wemos. It's a name used by several non-Wemos clones that have an ESP32 chip in a module form factor that is compatible with the original Wemos D1 mini.

The challenge is that these modules are not all the same. The differences are for example in the voltage regulator and how much current you can draw from it. Which can make something work fine with one "D1-ESP32" while not working with another.
