Hey guys, i decided to upgrade my graflex's blade to a neopixel blade. i also bought a new proffieboard v2.2 everything works good sound, sensors, power and aux buttons. the only problem is the blade. when the blade is connected nothing turns on. when the blade is removed everything works and if ill connect the blade while everything is working all stop and weird sound of a static tone is coming out from the speaker. first time it happend i thought someting is shorting the circuit in the blade so re-solder everything from the start. and then i checked the blade everything was working. then again using the blade with all the other components this weird tone is coming out the speakers and everything stops working.
any suggestions?
