The Elcano architecture features a series of microcontrollers connected over the automotive standard [[Communication |CAN bus]]. CAN is a no-host networking protocol with much of the overhead done in hardware. All Arduino processors are bare bones with no operating system. Messages sent over the bus are low bandwidth; any intense processing such as vision or lidar uses its own processor. Modularization reduces the size of the code running on any one processor. Reliability and security are enhanced since the core processors are not connected to the Internet and do not do machine learning.

		+	There are three RJ-45 connectors on the right edge for steering, motor control, and operator input. The bottom edge has other connectors. J13 has power connectors: Ground (black), 0/12/24V output for brakes (green), 24V (purple), 12 V (orange), and a 0/12V output.
		+
		+	J12 contains CAN HI, CAN LO, Ground, Connection signal from docking couple, and emergency stop button.
		+
		+	J10 has the once per wheel revolution pulse, Ground, output to an LED, and steering on/off.
		+
		+	J11 has output to show the state color on an LED with Red, Green, Ground and Blue.
		+
		+	J9 is a serial line with 5V, Tx2, Rx2, CTS, RTS and ground.
		+
		+	The screw terminals on the motor shield provide Ground, 12V power, two lines for Motor A (steering} and two lines for Motor B (gate raise for decoupling). Signals sent to the motor shield will put 12V or ground on the two lines to make the motor move in one direction or the other. With ground on both lines the motor does not move.
