This is a PWM cable, also known as a "servo extension cable." 22 gauge wire is used in these cables, and the body of the cable is jacketed with black heat shrink tubing. Notice that these are not 3-wire ribbon cables, like all other PWM cables. Universal servo connectors are on each end, with a female connector on one end and a male on the other.

Specifications

• Gauge: 22 AWG
• Length: 24 in.
• Weight: 0.036 lbs
• Wire Colors: white, red, black
• Wire Jacketing: black heat shrink tubing

This 6 in. long cable is designed specifically for the 2x5 pin data port on the Talon SRX to provide external inputs. It can be used to connect the Talon SRX to feedback devices such as potentiometers, limit switches, analog & quadrature encoders as well as providing other future expansions options beyond what is currently supported.

This cable can be used with the following list of products:

• Talon Tach (am-3778)
• Talon SRX Encoder Breakout Board (am-2633)
• Talon SRX Analog Breakout Board (am-2634)
• SPARK MAX Brushless and Brushed DC Motor Controller (am-4261)
• Lamprey Absolute Encoder (am-4179)
• SRX Magnetic Encoder (am-3445)

The MINI® Fuse is the standard for vehicle circuit protection. Its miniature design meets the need for more circuits to be protected while utilizing less space, and its ability to cope with high temperatures in adverse environments makes the MINI® Fuse of recommended choice for protection.

This mini fuse can be used in our Power Pole Distribution Board (am-3699), as well as a replacement in the Power Distribution Panel (am-2856)

Our Robot Signal Light is designed to work with the robo-RIO's RSL port to provide a quick visual indicator of robot status. This is not the 855PB-B12ME522 light specified by R70 of the 2017 FIRST Robotics Competition manual, but it does provide similar functionality.

We're offering this product so teams can use all the diagnostic features of the robo-RIO at an affordable price when legality and compactness isn't a priority. Our light housing is larger, and it is wired with two spade connectors. There is no polarity on the light housing, so it is not possible to wire backwards. 

To wire this light, we recommend our 2-wire cable (am-2133) and either soldering to the spade connections or using a female spade connector available separately.

Specifications:

• Weight: 0.1085 pounds without lead wires
• Height: 3.23 in. from top of dome to bottom of mounting stem
• Dome height: 2.09 in.
• Dome diameter: 2.24 in.
• Mounting stem diameter: 0.850 in.
• Mounting threads: M22x1.5, nut included

Have you lost OpenMesh Radio power during a match because the barrel came unplugged? You can keep that from happening ever again by using this Power Over Ethernet (POE) injector. This injector inserts POE power to a CAT5 Ethernet data cable on the unused Ethernet pins 4,5(+) and 7,8(-) allowing you to stop the worry about the barrel connector failures.
 

The barrel connector will still need to be used but it can move to a more secure location that can be wrapped with electrical tape to keep it in place better than attempting to tape it to the back of the OpenMesh Radio.
 

Plug in the RJ-45 of this unit to your roboRIO, plug the same 12V barrel connector from your Voltage Regulator Module (VRM) into the power port, securely tape it in place with electrical tape (better than awkwardly to the back to the OpenMesh Radio), and run an Ethernet cable from the female port to the Ethernet port closes to the power input on your OpenMesh Radio.

Specifications

• Length: 9.5 in.

This is the PD panel being used in the 2015 FIRST Robotics Competition Kit of Parts.

The Power Distribution Panel (PDP) from Cross the Road Electronics is the latest DC power interface for competition robotics. The PDP uses CAN to connect directly to the roboRIO and allows for individual current monitoring on each channel.

Replacement 20 Amp Mini Yellow Fuse (am-3605) & 10 Amp Mini Red Fuse (am-4053) are available as well.

Inputs:

• 12V DC Input (designed for FRC-legal battery). We recommend using a 120A Circuit Breaker (am-2082) between your power source and this panel.

Outputs:

• 12V DC output
• (8) 40A Protected Channels (12V)
• (8) 20A / 30A Protected Channels (12V)
• (1) 20A Protected Channel (shared between PCM and VRM)
• (1) 10A Protected Channel (roboRIO)
• (1) CAN Bus (provides feedback to roboRIO)

The Voltage Regulator Module (VRM) is a DC to DC convertor that is capable of both boost and buck voltage regulation. The device features two independent SEPIC (Single Ended Primary-inductor Converter) regulators allowing the input voltage to be above or below the desired output voltage. There are two regulators (one 5V and one 12V) each with two current limiting PTC’s (500mA and 2A). Reverse polarity protection is included.

The VRM has been used in the 2015-2021 FIRST Robotics Competition Kit of Parts.  As of Sept 10, 2020 according to FIRST blog these will continue to remain competition legal in future years.
