    J'ai placé une résistance de 10 ohms. La led est pilotée par une sortie pwm de l’Arduino.

    Модуль очень удобный, так как можно строить блочно сменную конструкцию. Цена низкая, что очень приятно. Купил аж 6-ть штук, для разных игрушек-самоделок. Жако, что два из последних были плохо сфокусированы (вместо точки - полоска), пришлось повозится самому с фокусировкой.

    The order was received well within the shipping time, the quality of the shipping, the packeging and the product itself was outstanding. I can recommend Banggood to everyone and I will certainly order again.

    Simply perfect. Nothing more and nothing less. I was looking for such laser transmitter module and found here for unbeatable price. Will get more arduino modules for sure.

    All are working 100%. "-" is negative, "s" is either positive or the biased signal input. I can't figure out the middle terminal.

    Due to soft packaging one of the lasers was so severely bent one of the leads had snapped. Easy to fix w bit of soldering.
