Abstract: Stackable electronic devices are disclosed which can be stacked onto each other in such a manner that electrical contacts with one device mate with electronic contacts on other devices either above or below the device to create an electrical connection between the devices in the stack. Magnets or latches can be used to secure the stacked devices together. The contacts, as well as status indicators, are arranged in common locations on the devices and the devices can be capable of automatically configuring addressing, device capabilities, and wireless communication paths.
