Width in tech details is wider than the official espressif esp32-s3 devkitc-1. in a standard breadboard is a row of holes available on each side?

I haven’t gotten to do too much with mine yet, but yes it is a bit wide, however for the amount of available pins and 2 USB C ports one of which for UART this is a great configuration. In a standard 10(5x2) column breadboard a-e & f-j this is 9 columns wide, so you would only have 1 row available on a single side. Solutions online seem to be to get an oversized breadboard with multiple smaller breadboards attached together with a single bus bar between them. Or to take a second breadboard, remove the bus bar from one side and put them next to each other and have the pins from the ESP-32 in 2 breadboards next to one another. Or for a really hack way split the breadboard down the middle and separate the 2) 5pin halves and you can adjust the number column of pins you need.

Is the Vin on 5v or is there a range like 5v-12v that it can take?

5V operation, too much voltage may burn the module

What do the IN-OUT and USB-OTG solder pads do? When should i bridge these pads?

IN solder pads is for 5vin port,default is to do external power supply input after shorting and output keep 5V,USB is the type-c port on the left side of the module,The default is to press the boot button to display the serial port,After shorting, it will display the serial port after normal power on.

Can you please point me to a pinout of this specific device ? info in which gpio's are attached to onboard leds and buttons appreciated too.

The ESP32-S3 is an entry-level development board featuring the ESP32-S3 universal Wi-Fi + BLE MCU module, fully integrated Wi-Fi and BLE function. Most of the I/O pins on the module are divided into the pin header on both sides of the board for easy interference. The developer can connect peripherals with jumper wires or attach ESP32-S3 to breadboard. There are three inter-exclusive ways to power the power option board: USB-to-UART port and ESP32-S3 USB port (either or both), default power supply (recommended) 5V and G (GND) pin 3V3 and G (GND) pins.
