ESP32-EVB vs ESP32-EVB-IND

[DanKoloff]

All ESP32-EVB board variants use same PCB hence white print is the same. However, the Ethernet chip is different modification. One is suitable for wider temperature range. The regular version uses LAN8720A LAN8710A while the industrial uses LAN8720Ai LAN8710Ai.

Edit: Initial version had wrong chip variant.

It's a 8710Ai:

Yes, my bad. It is 8710A and 8710Ai. This is also visible in the schematic. I've edited my previous post. The chip on your board is the industrial version.

Still I understand why it is not clear, this doesn't seem to be mentioned on the schematic. I will speak to the designers to generate Bill of Materials (BOM) for each board variant so I can upload it to GitHub.

The ESP32-POE and ESP32-POE-ISO have a lot of differences in the design to galvanically isolate the power supply from the POE and from the USB hence they have different PCBs. Still the IND versions just have few different components.

It's just the question of how can the customer easily identify, check that he received the correct product.

I had doubts because the relays are weaker than the spec (but still within my requirements so it's fine with me)
