Key Features :

1. 1. Stepper motor is known by its property to convert a train of input pulses into a precisely defined increment in the shaft position.
   2. This is a high-quality motor that can be used for a long time without stuck.
   3. It has a quite stable performance during work and will not lose step.
   4. Low noise and big torque, this is a great choice if you need a stepper motor.
   5. Stepper motor can be widely used for a 3D printer, CNC engraving machine, etc.

Key Features:

• NEW IMPROVEMENT: Clear prints on the female header connector, more precise and easier to use the wire.
• The ELEGOO UNO R3 BOARD now uses an ATMega16U2 instead of the ATMega8U2 chip. Faster transfer rates and more memory.
• Control using ATMEL ATMEGA328P chip(the same with Arduino UNO R3)
• 100% compatible with the Arduino IDE and RoHS Compliant
• The Uno board can be powered via the USB connection.
