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.
This is the chain and sprocket kit for the IG42-DB4 robot platform. It includes 10 tooth and 15 tooth sprockets, 6 feet of chain, and 4 connecting links.
This is a pair of 10" wheels and shafts. The shafts are machined steel with a welded hub. They are for our Heavy Duty and Enclosed Heavy Duty ATRs. These will not work for our Standard ATRs.
