I'm using ESP32-WROVER-E and working to modify the pin multiplexing. I'm using several UARTs and would prefer to move the UART RX signals to some of the input only pins. This page states that UARTs (other than the programming UART) can be multiplexed to any pin. Then, this support page on the UART p...

I'm hoping to be able to distinguish between multiple versions of ESP32 modules (ESP32-WROVER-32D, ESP32-WROOM-xx etc). Are there any memory locations or parameters which can be used to identify these, like a hardware UID? I'm aware of MAC addresses and the external flash hardware ID's but I don't t...

Linda, I was able to find the TuV test report for this module under FCC ID 2AC7Z-ESPWROOM32UE, and found that the FCC 15C testing was done with an external PIFA antenna with 4.0dBi of gain, I assume peak. Farther in the report is an antenna requirement section stating "According to the manufacturer ...

Thank you Linda. Are you able to provide the test reports or exact antenna(s) used in emissions testing so that we better understand the antenna parameters used?

Still no reply via the sales contact form. Does anyone have this information?
Can anyone from Espressif reply?

I'm planning on using the ESP32-WROOM-32UE module in a shipping product and plan to leverage the wireless pre-certification status of the module. Typically, this comes with restrictions on which antennas can be used in order to maintain the validity of the pre-certification. For example here is a ta...
