how to power 4 dc motors and esp32-s3-wroom-1u at the same time
so i made the 4wd rc car, and i need to power both motors and the esp32 and was wondering if it would be smart to power the esp32 with same battery (8 AAs) that powers the dc motors and use a bus converter to lower it to 3.3v for the esp32

Yeah that sounds like an good idea. For VIN/USB input 5v is typically recomended
i comb through the datasheet but didnt see any vin https://www.espressif.com/sites/default/files/documentation/esp32-s3-wroom-1_wroom-1u_datasheet_en.pdf

Power Supply Options
There are three mutually exclusive ways to provide power to the board:
USB-to-UART Port and ESP32-S3 USB Port (either one or both), default power supply (recommended)
5V and G (GND) pins
3V3 and G (GND) pins
i might use a 3-2s bms
okay so my plan would be to use 8 AAs, and use l7805cv to lower it to 5v to connect it to 5v and ground
