ESP32-WROOM-32E-N16 Bootloader

[davidgbal]

I am about to use this module on one of my pcb designs -
ESP32-WROOM-32E-N16

From the Expressif Product Selector it is not clear to me if this module ships with a bootloader than can be used with PlatformIO via UART or the JTAG pins?

Yes. Every single ESP32 (regardless of type) comes with a hardcoded ROM containing a bootloader allowing it to be programmed via UART and if it has an USB peripheral, also USB. JTAG programming doesn't need a bootloader per se, but be aware that on chips containing an USB-JTAG-serial converter, JTAG is routed there by default; to make it accessible over pins, you need to burn an eFuse.

Thank you for the confirmation.
