ESP32 Forum

Hi,
I'm newbie with the esp family but I'm interested by this chip to make a high speed recorder in the 16Mo of the Embedded memory.
And I would like to make a usb msd to get the file stored in the chip.
First of all, I need to design my board , is there somes applications note about the design ?
I need some uarts / SPI / I2C and the USB.
Is there some board with this chip to start working on the code before making the custom board.
Thanks.

There's the ESP32 Hardware Design Guidelines as well as the datasheets of the modules we sell (ESP32-Wroom/Wrover). You can get devboards at various outlets (Mouser, Aliexpress, Arrow, Sparkfun, ...) that you can prototype your design on. Note that the ESP32 does not have a native USB peripheral; the USB port that most devboards have goes to a dedicated USB-to-serial converter. (The ESP32-S2 will have USB support; it's expected in Q1 next year.)

Hi,
Thanks for the links , I don't know about the wrover (thanks for the name).
I've found the ESP32-WROVER-B it look great but is the SRAM keeps the data when the power is off ?
Do you think it is possible to make a kind of ftp or webpage to download the files I've recorded ?
Thanks

No, SRAM looses its data on power loss. Yes, ftp or http is possible, look around on the Internet and you'll find plenty examples of people doing that.

that what I tought RAM is volatile but I was not sure.
The best solution to test my idea is the ESP-WROVER-KIT V4.1 , there is 4Mo in SPI flash, sdcard and wifi .
Thanks
