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 :

1. Tiny and lightweight with high output power. The servo can rotate approximately 180 degrees (90 in each direction) and works just like the standard kinds but smaller.
2. You can use any servo code, hardware, or library to control these servos.
3. Good for beginners who want to make stuff move without building a motor controller with feedback & gearbox, especially since it will fit in small places. It comes with 3 horns (arms) and hardware.

?Key Features :

1. 1. 1. 11 digital input/output pins, all pins have interrupt/pwm/I2C/one-wire
      2. supported(except D0)
      3. 1 analog input(3.2V max input)
      4. Micro USB connection
      5. Use BRT (Bias Resistor Transistor), easier into flash mode.
      6. 30% increase in radiating area, more stable.
      7. Dimensions : 35 x 26 x 8 (LxWxH) mm.
      8. Weight: 10 gm.
      9. Board Color : Blue
      10. Compatible with Arduino
      11. Compatible with NodeMCU
      12. Compatible with MicroPython

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.
• The Uno board can be powered with an external power supply.
• Excellent welding and production quality to make sure satisfied customer experience
• The RX and TX LEDs on the board will flash when data is being transmitted via the USB-to-serial chip and USB connection to the computer.
• We have always cared about the customer experience and improve the product function details.
