DollaTek L298N Dual H-Bridge Motor Driver Module - 5V-35V

High-Performance Driving: Utilizes the ST L298N chipset to provide strong driving capability and excellent anti-interference performance for your motor applications.

This volume provides an introduction to dessins d'enfants and embeddings of bipartite graphs in compact Riemann surfaces. The first part of the book presents basic material, guiding the reader through the current field of research. A key point of the second part is the interplay between the automorphism groups of dessins and their Riemann surfaces, and the action of the absolute Galois group on dessins and their algebraic curves. It concludes by showing the links between the theory of dessins and other areas of arithmetic and geometry, such as the abc conjecture, complex multiplication and Beauville surfaces. Dessins d'Enfants on Riemann Surfaces will appeal to graduate students and all mathematicians interested in maps, hypermaps, Riemann surfaces, geometric group actions, and arithmetic.

Integrated Power Logic: Features an internal 5V power supply that works when your driving voltage is between 7V and 35V, allowing you to use the 5V output for external components.

Dual-Channel Efficiency: The dual-channel H-bridge working mode creates higher working efficiency for controlling multiple motor outputs simultaneously.

Versatile Specifications: Supports a drive voltage of 5V-35V and a maximum drive current of 2A per single bridge, handling up to 25W of power.

Compact Design: Measuring just 43*43*27mm, this module is sized perfectly for integration into smart cars, robots, and small electronic enclosures.
