The next generation of FETtec's popular KISS flight controller has arrived! Featuring the latest STM32 G4 MCU with math accelerator for the ultimate in flight performance, MPU6000 gyro, 2 dedicated BECs for 5V and 16V switchable power, DSHOT2400 outputs for support of up to 8 motors, and dual 20x20 and 30x30 mounting holes.

This new "N" version simply means there is no onboard analog OSD chip.  Due to global shortages, the OSD chip was removed.  This only affects analog systems, there are no other restrictions and you can use the full potential of this FC as you are used to.  The use of external OSD boards and digital FPV systems still work fine.
