45.1	79	The case of the Lynxmotion PRO Smart Servo is in three parts: the main body, the cap and the mounting plate. Each of these three parts is milled from aluminum and anodized black.
	80
	81	Main Body
	82
	83	The main body is in the shape of a compact T, with the stepper motor located in the center.
	84
	85	Cap
	86
	87	The cap supports the top and bottom PCB which make up the electronics inside the actuator. The bottom PCB must be located at the rear of the stepper motor in order to make use of the encoder.
	88
	89	Mounting Plate
	90
	91	The mounting plate provides a convenient connection point onto which another actuator, clamp or bracket can be connected. As indicated above, it has the mounting pattern for the gearbox output for each of the three servo motors, as well as the clamp.

	107	RJ45 - CAN Communication
	108
	109	There are two RJ45 connectors which allow the servos to be daisy chained. Either connector can be used as the pinout is identical. More information about the pinout can be found on the LSS-P - Electrical page.
	110
	111	XT60 - Power
	112
	113	The actuators are powered via ONE of the two XT60 connectors. The second XT60 is to provide power to the next actuator in the bus. Never feed an actuator with two sources of power. More information about the power requirements can be found on the LSS-P - Electrical page.

45.1	133	Unlike many tabletop "Cobot" ("collaborative robot") robotic arms which use BLDC / frameless DC motors and measure the current needed for a motion, the LSS-P actuators use standard sized and industry proven bipolar stepper motors. These motors provide high torque at low speeds, but operate at a set current and therefore do not have a direct way of measuring the torque.
