The board inside this controller is the newer design. If you are planning on adding your own back buttons or making other changes you need to be aware that some remap kits or back button kits will not work with this controller. For example the extreme rate rise4 remap kit or the TOMSIN programmable remap back paddles will not attach to this controllers board and will not work. The boards model number is BDM-030. Check your kits to make sure they are compatible so you don’t screw yourself. If your planning on adding a new battery, face buttons or just using it as is, you should be fine tho.
