The XT30 connector is used for connecting a battery and powering a Control/Expansion Hub. Each Control/Expansion Hub has both a Male and Female XT30 connector, as determined from the metal contacts, not the plastic housing. While either connector can provide power to the hub, it is the convention to use the male connector for "power in" to the hub, and to use the female connector for "power out" to a connected secondary device, like an Expansion Hub or XT30 Power Distribution Block, from the single battery source. Passing power from one device to another in a chain is often called "daisy-chaining."
Most teams will want to use pre-made cables which can be conveniently sourced from the REV Robotics website. However, teams can also make their own cables. These connectors are solder-cup style, do not require any crimping tools, and are available from various online vendors. Because these connectors are an open design, they are manufactured by a variety of sources and quality may vary. AMASS branded connectors are recommended, and are what is used on REV products, but there are many other quality vendors available.

The REV Robotics Control Hub (REV-31-1595) connector selection provides a robust high-density solution for the user. All connectors are keyed and locking except for the Servo, 5V auxiliary power, HDMI , and USB ports.
For teams that want to try crimping their own cables, or to find more information about the connectors, Table 3 lists the appropriate part numbers.
Connector Specifications
10A Continuous Current (16AWG)
3.96mm Pitch
Accepts 22-16AWG Wire
The JST PH style connector is used for motor encoder, analog, digital, I2C, RS485, and UART connections on the Control Hub and Expansion Hub. These are all 4-pin connections except for the RS485 and UART which are 3 pin. The connectors are keyed (they only insert in one orientation) and are friction locking. Below the keying feature aligned with the cable is shown.
REV Robotics recommends in most cases that teams use pre-made cables because the quality of the crimp is better when made using industrial tooling. These cables can be bought directly from the REV Robotics Website or through other online vendors.
For teams that want to try crimping their own cables, or to find more information about the connectors, the table below lists the appropriate part numbers.
Connector Specifications
2A continuous current (24AWG)
2.0mm pitch
Accepts 32-24AWG wire
Motor Power connections on the Control Hub () use the JST VH style connector. This connector is keyed and locking with a small latch, seen below, which must be depressed to release the cable.
REV Robotics recommends, in most cases, that teams use pre-made cables because crimp quality is better when made using industrial tooling. These cables can be purchased directly from the or through other online vendors.
