The most advanced connection to the DevDevil is provided by the I
connecting to a controller and serial TTL capability is not available. It requires a connection directly to your project, best
accomplished using a breadboard and the included cable of the same name. Power is usually applied from the
breadboard, but can also be supplied directly to the DevDevil using the optional AC power adapter. To dive right into your
