ATMEGA32U2 does not have I2C pins SDA/SCL. The ATMEGA32U4 does have a I2C interface (its labeled 2-wire serial interface in the datasheet).

Do you have a high-quality image of the pcb fladhcat ? Under and above.please send for me
 
What are you attempting to accomplish, are you building your own flahscat?

Is this guy trying to pirate the device?
 
i2c is only supported on the ATMEGA32U4 fcusb version and newer models , the old ATMEGA32U2 fcusb versions were phased out ages ago and did not support i2c amongst other things.

The old FlashcatUSB used AT90USB162. The current FlashcatUSB still uses ATMEGA32U2 (which does not have I2C hardware), however it is configured to be fast enough to emulate I2C in software. So technically any GPIO pin could be used for I2C if is supports open-drain and push/pull.
 
Hello, Friend.Do you have the schematics of this device? Or a forwarding address from the site of the device. Is it supporting i2c and 93xxx / 25xxx

Actually my first FlashcatUSB was the pirated one by TIAO called "Black Flash USB+," but this is based on old design and no way to have the latest firmware support. Now I only trust the original because it keeps getting better and better!

That's right. that's the old model.
You don't have the new schematics?
Model used by atmega32u2 and support the new software.
