ESP32 WROVER dev board with all pins

Post by liudr » Thu Jun 21, 2018 7:37 pm

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 :D 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.

Oh, that's why :o
Thank you Roberthh for saving me one batch of boards. I was gonna use those pins for serial port 2.
