This pololu A4988 stepper motor driver is installed in a very largme amount of DIY 3D printers. It can be considered as the reference stepper driver amount stepper drivers. Courant dmaximum de bobine: 1.75A Max avec dissipateur. Max Current per coil: 1.75A
Allows to drive Stepper motors. Max coil current: 2.2A More powerfull and more precise than the commonly used A4988 Needs a good air flow below the chip THe heatsink is optional if you have a good air flow, but needed in order to use the max current. Maximum resultion of 1/32 micro-steps supported by 8bit micro-controlers such as Atmega 2560.
Inductive probe for 3D printer Input voltage: 6-36V Model:LJ12A3-4-Z/BX 3 wires ( brown, blue, black) Output type: NPN NO (normaly open) Diameter of the blue probe: 10,5mm Diameter of the thread: 12mm Sensing distance: 4mm Current consumption: max 200mA Size: 5.8x 1.2cm Wire size: about 115cm Weight: 44g
Ceramic screw diver. Great tool to adjust various kind of electronic device sensitive to Electro static dischanges such as Steper motor drivers. Model: CD-20 Type: Flat screw diver Width: 1.8mm Diameter: 0.4mm Ideal for 3D printer stepper drivers Warning: Can break easily
