Mini 4CH 4 Channel Motor Drive Driver Shield – L293 / L293D Mini 4CH motor driver shield designed as an Arduino expansion board module. Based on the proven L293 or L293D driver ICs for reliable motor drive performance. Supplied as a pack of 20 pieces — convenient quantity for workshops, classrooms, labs, or bulk projects. Key benefits — why you need it Simplifies motor control: provides a compact, board-level solution to drive up to four motor channels from Arduino-compatible controllers, reducing wiring and development time. Reliable and familiar components: uses L293/L293D driver chips that are widely supported and understood, helping you avoid compatibility surprises during prototyping. Space-saving design: mini form factor fits compact projects and keeps your build tidy while still delivering multi-channel control. Bulk availability: 20 boards in one lot make it easy to equip teams, run multiple simultaneous experiments, or maintain spare units for rapid replacement. What it does and how it helps Function: provides four motor drive channels on a small expansion shield that interfaces directly with Arduino-compatible boards, enabling coordinated motor control without separate driver modules. Compatibility: built specifically as an Arduino expansion board module, intended to plug into or work alongside Arduino hardware and common Arduino development environments. Performance: leverages L293/L293D driver ICs to deliver dependable, predictable motor switching and control behavior across projects. Practicality: reduces component count and assembly complexity by consolidating motor-driving circuitry onto a single shield per board. Notable attributes Model: Mini 4CH 4 Channel Motor Drive Driver Shield. Driver ICs: L293 or L293D (as specified). Form factor: mini shield designed for Arduino expansion use. Quantity: 20 pieces included (useful for bulk projects and multiple builds). Construction: standard PCB-mounted driver shield using the referenced driver chips for motor control. Typical applications and use scenarios Small robotics: drive up to four motors for mobile robots, articulated robots, or multi-wheeled platforms where compact, reliable motor control is required. Education and workshops: supply entire classrooms or maker groups with consistent driver shields for hands-on Arduino motor control lessons and experiments. Prototyping and testing: quickly evaluate multi-motor control schemes, test motor driver behavior, or run parallel experiments without sourcing individual driver modules.
