Mini Driver p/ 2 motores DC 1.5A (HR8833)

DESCRIÇÃO EM PORTUGUÊS BREVEMENTE DISPONÍVEL

Se tiver alguma dúvida neste produto não hesite em contactar-nos.

*Atenção: as imagens são meramente ilustrativas.

This is a ultra compact size Dual-H-Bridge dc motor driver (Based on HR8833), which could drive two way 1.5A DC brush motors up to 10V . It has the same footprint as your thumbnail suitable for projects with limited spaces.
 

Both sides of the module are desgined with standard XH2.54 pins, which allows you to plug it on a breadboard or prototype board.
