REV Servo Hub and Smart Servo V2 Arrive

The REV Servo Hub and Smart Servo V2 are now listed in REV Robotics' $400 Servo Bundle V2. It combines one hub with six servo units and supporting hardware. REV designed the package for teams building mechanisms that need more than a controller's usual servo ports. The company says the hub can control up to six servos through one interface.[1][3]

What does the REV Servo Hub and Smart Servo V2 bundle include?

The REV Servo Hub and Smart Servo V2 bundle is a parts package, not a completed robot subsystem. REV lists four Balanced servos, two UltraSpeed servos, one Servo Hub, an SRS Programmer, servo horns, arms, PWM cables, and cable clips. The company lists the bundle as REV-45-3248 at $400.[1]

REV lists both servo variants at $32.50 when sold individually.[2] At 7.4 V, REV lists the Balanced version at 0.12 seconds per 60 degrees and 16.7 kg-cm stall torque. It lists UltraSpeed at 0.035 seconds per 60 degrees and 6.2 kg-cm.[2]

That split makes the package easier to read as a starting point for mixed mechanisms. It does not establish which configuration fits a specific competition robot or task. Teams still need to calculate loads, geometry, battery demand, and applicable competition rules.

REV lists four Balanced and two UltraSpeed Smart Robot Servo V2 units in the $400 bundle.[1]

How does the REV Servo Hub change servo wiring?

The REV Servo Hub and Smart Servo V2 setup puts up to six servo channels behind a single communication interface, according to REV's documentation. The hub supports REV ION and REV DUO systems, and REV says it removes the need for additional PWM cabling between the hub and robot controller.[3]

The electrical limit matters. REV specifies a maximum total output of 15 A, with a maximum 3 A channel output figure, and cautions users to add connected servos' stall currents when checking the total.[3] A six-port layout does not mean every combination of six servos can run at maximum load at once.

The company documents USB, RS485, and CAN connectivity. REV Hardware Client 2 and REVLib provide some per-channel features, including current measurement and switchable output power. The FTC SDK does not provide those features.[3]

What can Smart Robot Servo V2 units do?

REV says the SRS Programmer lets users set each Smart Robot Servo V2 to standard angular, custom angular, or continuous rotation operation. Its default angular range is 270 degrees, and its maximum programmable angular range is 280 degrees.[2]

The servos use steel gears, a 25T spline, and a 4.8 V to 7.4 V rated voltage range, according to the product page.[2] Those are manufacturer specifications, not independent durability or performance results.

The immediate news is availability and packaging, not a claim of field performance. REV's public product materials describe the hardware and its intended configuration options; they do not provide comparative test results for a completed robot mechanism.[1][2]
