K SMD Motor Driver
Dave Hrynkiw
February 13, 2003
Got a new kit for you - the K SMD L293D Motor Driver. No, no, the SMD isn't "surface mount" - it's the Secret Motor Driver! This L293D-based motor driver fits secretly inside most standard servo cases like the Futaba S3003/S148, and our own GM4 gear motors. It replaces the low-voltage original electronics with LED-indicated, 1.2A powered, 36V capable, logic-compatible signal circuitry!
The 'Secret' motor driver board is ideal for mini-sumo robots, breadboarding motor circuits, or anywhere else where you need a compact, reliable circuit to drive your motor using standard logic level (not servo PWM) signals.
Introductory Special: Get two for $20USD ($30CDN)!
