E3D wear-resistant 0.40 mm nozzle made of hardened steel for 1.75 mm filament. Compatible with E3D v6 kits and to be used for filament filled with carbon fibre or other abrasive materials.
The drive module can directly drive four DC motors, drive the car chassis is 4WD 4 choice .Driving battery big up to 1A generally smart car motor current 100-300MA only four are sufficient to meet the control requirements .While leaving Road stepper motor interface can drive Road five line four-phase stepper motor or Road, two-phase four-wire stepper motor, very suitable for precise control requirements.
The Device is a monolithic integrated high voltage,high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors.
