Re: ESP32-S3-WROOM-1 flashing via usb vs UART


For usb programming, should I just use a 2-pin header for GPIO 19-20 and add buttons for EN,RST pins, then just connect D+ and D- to usb-c connector
Yes, that should be enough.

You need GND too. If you have no need to manually reset it you dont need buttons for EN and reset.


Thank you, but ...

Re: ESP32-S3-WROOM-1 flashing via usb vs UART


If I use a CP2102 module like this: CP2102 flash the esp32, should I just put a 6 pin header for RX,TX,VCC,GND,EN,RST and use 2 transistors before EN and RST pins.

What you need to flash it is just RX and TX. The transistors which you can see in dev kit schematic are driven by UART ctrl signals ...

ESP32-S3-WROOM-1 flashing via usb vs UART

Hello, I am designing a device which uses esp32-s3-wroom-1 to get data from SPI and send it through WiFi.

My first questions is, I think I only need power,SPI and flashing pins to attach in my schematic and no other component because Wroom-1 module already has the parts in esp32 s3 reference sheet ...
