Grove Electromagnet

Un module agréable, mais résistant uniquement lorsqu'il est en contact direct avec un matériau ferreux. J'ai essayé de mettre une protection ABS de 0,2 mm dessus et elle ne pouvait en réalité contenir plus qu'un trombone.

Works well - the board provides the necessary transistor, protection diode and resistors so no additional components are required. Note that you don't need a GrovePi kit or anything to make this work, just connect it to a 5V supply, ground and logic input as indicated. Works fine with a 3.3V logic signal (e.g. from a Raspberry Pi).

A nice module, but only strong when directly contacting ferrous material. I tried putting a 0.2mm ABS cover over it and it effectively couldn't hold more than a paperclip.

Fast delivery and works great

Works great, heats a little. I test it with a 0,5kg cylinder. I can pull it, but not lift it.
