Re: ESP32-WROOM-32E Minimum implementation without USB
Thank you. If we were to try to implement a more automated programmed method with an external UART, how would we deal with the DTR issue described above? This solution would definitely be preferred, so any information you can provide would be very helpful A button based procedure is not preferred, b...

Re: ESP32-WROOM-32E Minimum implementation without USB
Thanks for the reply sprite. It looks like many standard USB-UART cables (including the FT232 that we plan to use) don't feature the DTR line that is leveraged on the EVAL board. Any recommendations for how to work around this? Also, can this boot procedure be simply coordinated with a button press ...

Re: ESP32-WROOM-32E Minimum implementation without USB
Looking to bump and clarify some revised requirements
I've removed the requirement for UART firmware programming from our internal interface (though if it's possible, we'd like the option).
Questions 2 and 3 are still remaining, though #2 is the current priority

ESP32-WROOM-32E Minimum implementation without USB
Hello, I'm working on placing the ESP32-WROOM-32E onto an existing PCB design. The device will be powered from existing onboard 3.3V, and will not be featuring a USB connector/USB5V/onboard USB-UART converter. Currently, I'm referencing both the ESP32-WROOM-32E data sheet section 6 "Peripheral Schem...
