Could somebody explain how one can set the lock-bits so that one cannot write or read what is on the Arduboy? I am assuming a USBasp can do that, but I don’t know how one would just set/programm these lock-bits. (I am aware that this would prevent uploading of new sketches unless the Arduboy is completely erased and a new bootloader is programmed.)
@eried How long are the pogo pins that go together with your 3D design? The ebay link is not valid anymore.
