Matek F405-STD Betaflight Flight Controller

This is the F405 STD Matek systems, fully compatible with both Betaflight and iNav.  This flight controller uses the ICM-20602 gyro connected via SPI to product 32Khz gyro updates to detect quadcopter’s motion for precision control.  In addition this flight controller packs a betaflight OSD giving you the ability to view OSD information and also set flight controller parameters via the OSD menu.  More importantly this flight controller is designed to be stack-able with the Matek FCHUB-6S to make for a reliable and truly 6S compatible flight stack.  Dont need 6S?  Then this FC also stacks with the FCHUB-VTX to have a excellent VTX with telemetry.     But the advantage of this stackable nature is that in a serious crash, if something breaks you have the option of replacing a component such as the FC, or the PDB which is abit cheaper than replacing a all in one board.  Furthermore this FC also has a SD card slot allowing you to log at much data as you want.

Bottom line, if you are looking for a solid FC that doesn’t break the bank, works on both Inav and Betaflight use.. the F405-STD is the one for you.
