 # CBUnmanned H743 Stamp
 
-The [CBUnmanned H743 Stamp](https://cbunmanned.com/store) is a flight controller loosely based on the FMUv6 standards & is designed for low volume OEMs as a drop in way to add ArduPilot to their custom hardware builds. It is a part of CBUnmanned's wider ["Stamp" Eco-System](https://wiki.cbunmanned.com/wiki/cbunmanned-stamp-eco-system), which brings together all the typical avionics hardware into a neat custom carrier PCB. Mounting footprints and symbols are available along with examples of basic usage on the  [Wiki](https://wiki.cbunmanned.com/wiki/cbunmanned-stamp-eco-system/h743-flight-controller).
