# One family of nodes.

Source: https://checkmatedynamics.com/products.html

Products | Four families · one bus

Every product is a finished unit that works on its own and joins the same USB-C bus as the rest. Learn one and you know the next: same cable, same status light, same app.

**A** Move

## Motor nodes with everything inside.

Driver, encoder, controller and gearbox built in and calibrated as one unit. Reducers are part of the nodes, not separate parts.

**A1** SmartStepper 17 From USD 79 planned

Closed-loop NEMA 17. Board, direct-drive node, or with a 25:1 metal cycloidal.

**A2** SmartServo G From USD 89 planned

Brushless servo for 2804 and 5208 gimbal motors, direct drive or cycloidal. The Leader’s joints.

**B** Sense

## The scene around the robot, the angle inside the joint.

Contour | **54 × 42 zones**

Diagram

**B1–B2** Contour, Contour Wrist Waitlist

Metric time-of-flight depth over USB-C, synced to your cameras. The Wrist version rides on the gripper.

**B3** Output encoder USD 29 planned

Reads a reducer’s output angle directly. Standard on geared nodes, sold for retrofit.

**C** Sync

## An instrument for the station.

The Sync Beacon doesn’t measure the scene or a joint. It checks that every other stream agrees on time, independently of the recorder, and certifies each episode. That’s why it has a family of its own.

[Sync Kit](https://checkmatedynamics.com/sync-kit.html)

From USD 1,490 per station, planned. Patent pending.

**D1** Hub 8 Pro USD 399 planned

Eight node ports, per-port power and CAN, hardware e-stop.

**D2** Bus cable In the box

Power, USB and CAN on one USB-C cable. An anodized Cable Clip holds it in the port; one comes with every node.

**D3** I/O tile USD 19 planned

Qwiic and AUX ports for SmartServo G.

**E** Systems

## Assembled from the families above.

Nothing inside is a special variant. Each system is a list of catalog numbers plus a little structure.
