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 an SST tracked robot platform equipped with 32-millimeter motors, a motor controller and a tethered remote. It has a pan/tilt camera with high power LED lights. This is a rugged treaded robot platform.
This package includes all the items you would need to make a robot drive to GPS waypoints autonomously.
