I'm using an ESP32 WROVER dev board marked TTGO. It has a lot of features including sd card slot and 3D antenna. I wish it has brought out GPIO 16 and 17 like the WROOM board I have. Here is a vendor selling the board I have:

BTW, has anyone tried this batch flash tool?

You could call this a dev board too Why then are the pins that are supposed to be GPIO 16 and 17 marked as GND? Second picture, right pins, below IO18 and IO5.

Gpio16 and gpio17 are needed for the psram chip.
