Can STM32F407VGT6U acts like STM32407VGT6?

[Karuniawan_Amah]

I just bought STM32 Discovery Board with STM32F407VGT6U ICs, the thing is i use the stm32duino extension on arduino IDE, and on one laptop we can't upload it, on other laptop the Board can't send Serial data, previously i use the STM32F407VET6 series and work just fine. also i hear that the 'U' at the end stand for the Java dedicated device? is it true? and can i make it like VGT6 basic series? also some people said you need to erase it to make it like normal, how to do it? Thank you, any help is appreciated

The meanings of all the letters at the end of the part number are described in the Datasheet

No it's not Java. It means that it for development/education purposes, and is Unlicensed for commercial applications, so IP licenses related to CAN, Ethernet, etc have not be paid.

Basically ST paid less for the part in terms of internal accounting.

The U and Non-U part will be functionally the same. The VG vs VE is just the amount of FLASH tested on the die.

The amount of glare in the picture makes it practically unreadable. Use macro mode if available, and a closer / oblique angle to minimize glare.

This was the Java one  STM32F407IGH6J

i still kinda confuse tho, maybe cause i use arduino IDE, but the Serial print not work there, works fine with older board VET series one, also when i plug it in, it appears like on the image here. it like it's acts like flashdisk or other save device
