#40894 Hello,

all the esp module contain the esp chip itself, an isp Flash Memory chip and a PCB Antenne. Is this Memory chip necessary? can i load the Code directely to the esp chip without this additional chip?

I have tried it using arduino IDE but that wasn t succeded. So can i say that the bootloader in the esp chip is written so that the user Programm is always saved in an additional SPI chip Memory?

If yes can i use any spi chip Memory? or other conditions must be respected? As i have checked the different modules contain different spi chip Memory.

what are you thinking? thnx.
