9 -**Electronics**: The V1 system was based on the BotBoarduino Arduino-compatible microcontroller and the SSC-32U servo controller. A variety of servo cable extensions, wiring harnesses and related cabling was used to connect everything together. The V2 system focuses on smart servo cables while still permitting RC control. The main electronics for the V2 include only an adapter and power hub.

11 -**Hardware**: The Lynxmotion Servo Erector Set has always included both metric and imperial dimensions, and the V1 system used almost 150 different screws, nuts, washers, standoffs and related accessories. The V2 reduces this down to less than 10, focusing 2-56 threaded pan head screws and 2-56 nuts for bracket connections, and M3 screws for standoffs and servo horn mounting.

13 -**Main Parts**: The Lynxmotion SES V1 system uses several models of Hitec RC servo motors, while the Lynxmotion Smart Servo Motors form the basis of the V2 system. Details about the smart servos, their features and more can be found [[here>>doc:Lynxmotion Smart Servo (LSS).WebHome]]. The first SES system used a variety of different Hitec RC servos, and brackets were designed to adapt these servos to to the Erector Set. Although a standard RC servo case size existed for many Hitec servos, several series of brackets had to be created to accommodate different servo sizes (micro, standard and large). Some brackets were designed to have one specific application (for example the body panels for a specific hexapod design) while most were meant to be as modular as possible. In all around 70 brackets were created for the V1 SES system. Disregarding the Hitec RC servo-specific brackets, the remaining brackets from the V1 can mostly be used for the V2 system. The new Lynxmotion Smart Servos were designed to be used with the v1 bracket system in order to create a modular robotic building system called the Lynxmotion Servo Erector Set (S.E.S.) v2. It is therefore entirely possible to create a new robot which uses elements from both the V1 and V2 systems. The SES V1 provided an option for 1:1 external gearing, and the V2 system also includes the option for adding external gears (1:1 and 1:3) which can be mounted to the servo itself as well as using an external gearbox bracket. Gears use a standard pitch of 16, allowing them to be compatible with other spur gears and gear racks of the same pitch.

31 += SES Mounting Pattern =

33 +The SES mounting pattern is based on two holes which are used for mounting objects to a Hitec standard servo horn such as the Hitec HS-422. The mounting pattern involves:

52 +**SES V2b Pattern**

54 +Several of the brackets have an opening which allows the SES V2 cable(s) to pass through. The aluminum clamping hub also has this opening, so when used with carbon fiber tubing, the wires can be passed within the structure.
