Have purchased 2 of this :
https://www.hobbyking.com/hobbyking/sto ... Board.html
After replacing, the buzzer start to buzz when I connect the battery to the socket, without activating the On/Off switch.
It stop buzzing when On/Off swirtch is pushed to On.
This happen with both mainbord.
The display is Ok and the menu is working.
Does both board have an error or is there a procedure to follow to activate a new board ?
Any out there with an answer ?
Thanks.
