The ULN2003APG High Current Driver has 7 NPN Darlington arrays in a 16-SOIC package. This is perfect when you need to use a microcontroller to toggle a relay or control high power LEDs.
The SDR LED Light boards are perfect for directional lighting applications in robotics.
The SN74LS241N Tri-State Buffer allows you to toggle an output between the input and high-impedence. This is useful when working with 1-wire TTL interfaces such as the Dynamixel Servos.
A master battery disconnect switch is a lever-operated battery cutoff switch that will disconnect power for the battery circuit.
This is a Pre Built robot that utilizes 4 omni omni-wheels to vector it in any direction. By changing the speeds and directions of the motors the robot can drive in any direction without needing to turn.
