I bought recently a esp32 wrover chip. Now i want to flash this without a breakout board. Can i also use this wiring for flashing:

Also, do i need specific driver for windows 7 to do so? Or can is just wire everything up and flash it with esp idf / arduino ide?

Weird, it's working there (esp idf versions are the same): Here's the test menu, pick your combo: (1) "can probe SD" [sd][ignore] (2) "can probe SD (using SPI)" [sdspi][ignore] (3) "can write and read back blocks" [sd][ignore] (4) "can write and read back blocks...
