Yes I am using using dev boards with ESP-WROOM32 modules. Do you know of any modules that ship without flash?

It also seems as if the ESP-WROOM32 modules should be fused to only use 3.3V since there is already flash in the module that will be bricked otherwise.

I have found that pulling MDI0 high and setting VDD_SDIO to 1.8V mode that the on board flash stops working. I was under the impression that this flash was powered via VDD3P3_RTC. Is there any means other than a custom board that allows the onboard flash to be used and still run SPI0 in 1.8V mode? O...
