The maximum speed for a 28byj-48 stepper motor is roughly 10-15 rpm at 5 V.
The 28BYJ-48 motor runs in full step mode, each step corresponds to a rotation of 11.25°. That means there are 32 steps per revolution (360°/11.25° = 32). In addition, the motor has a 1/64 reduction gear set.
The power consumption of the motor is around 240mA.
The ULN2003 is one of the most common motor driver ICs, consisting of an array of 7 Darlington transistor pairs, each pair is capable of driving loads of up to 500mA and 50V. Four out of seven pairs are used on this board.

This kit introduces quite a few electronic principles, its fun and not difficult to build. This is a self-build DIY smart tracking robot car kit. It is an introductory electronic kit designed to help kids, electronic enthusiasts, and novices learn about basic electronic knowledge like soldering and simple circuits(photoelectric sensor circuit, voltage comparator, motor driving,ir sensors etc.) The smart kit is designed based on the principle of infrared sensor and light reflectivity difference when the light emitting on the white and black items
The assembly steps:
Step 1: Welding circuit
Soldering part is simpler, welding sequence according to the principle of component level from low to high, the first welding eight resistance, is important to use multimeter to confirm resistance is correct, D4, D5 R13 R14 can temporarily not welding, integrated circuit chips can temporarily not inserted
Step 2: Mechanical assembly
The red line is connected to the 3V positive power supply, the yellow line grounding, excess wire an be used for motor wire.
Step 3: The installation of a photoelectric circuit
Photosensitive resistance and light-emitting diodes (note polarity) is reverse-mounted on the PCB, and the ground distance is about 5 mm, both photosensitive resistance and light-emitting diodes are 5 mm distance. Finally, you can power test.
Step 4: Vehicle debugging
The right direction is along the universal wheel direction, if you press and hold the left photoresistor, the wheels on the right side of the car should be rotated. Press and hold the right photoresistor, the wheels on the left side of the car should be rotated, if the car driving back, can also exchange the wiring of two motors, if the one side normal and the other side back up, as long as you can swap wiring of back side.
Note: We don't supply any manuals please note this before you buy it.

This high-power, 130-size brushed DC motor can be used as a direct replacement for lower-power 130-size motors to get more torque and speed out of your gearmotor, but it will also draw more current and typically wear out faster.
It has a recommended operating voltage of 1.5 V to 3 V, but it can operate at higher voltages to provide more power in exchange for longevity of the motor.
Approximate specifications at 3 V: free-run speed of 20,000 RPM, free-run current of 350 mA, stall current of 4 A, stall torque of 55 gf-cm (0.75 oz-in).

Kit includes:
- Laser cut chassis
- Raspberry Pi camera mount
- 2 x super-grippy moon-buggy wheels
- 2 x push header motors (298:1 ratio)
- 0.5" front castor wheel
- Jumper leads
- 2 x motor mounting brackets
- 2 x battery clips (battery optional and not included)

Fire four solenoids, spin two DC motors or step one bi-polar or uni-polar stepper with 1.2A per channel (3A peak) using the TB6612.
We really like these dual H-bridges, so if you want to control motors without a shield or HAT these are easy to include on any solderless breadboard or perma-proto.
We solder on TB6612 onto a breakout board for you here, with a polarity protection FET on the motor voltage input and a pullup on the "standby" enable pin. Each breakout chip contains two full H-bridges (four half H-bridges). That means you can drive four solenoids, two DC motors bi-directionally, or one stepper motor. Just make sure they're good for 1.2 Amp or less of current, since that's the limit of this chip. They do handle a peak of 3A but that's just for a short amount of time. What we like most about this particular driver is that it comes with built in kick-back diodes internally so you dont have to worry about the inductive kick damaging your project or driver!
There's two digital inputs per H-bridge (one for each half of the bridge) as well as a PWM input per driver so you can control motor speed. Runs at 2.7V-5V logic. The motor voltage is separate from the logic voltage. Good for motor voltages from 4.5V up to 13.5V! This wont work well for 3V motors.
Comes as one assembled and tested breakout plus a small strip of header. You'll need to do some light soldering to attach the header onto the breakout PCB. Arduino, motors, and power supply not included. Check out the handy tutorial on assembly and wiring!

- Current Limit: 1.2A
- Size: 27mm x 19mm x 3mm / 1.1" x 0.7" x 0.1"

Let your robotic dreams come true with the new DC Stepper Motor HAT from Adafruit. This Raspberry Pi add-on is perfect for any motion project as it can drive up to 4 DC or 2 Stepper motors with full PWM speed control.
Raspberry Pi and motors are not included.
Since the Raspberry Pi does not have a lot of PWM pins, we use a fully-dedicated PWM driver chip onboard to both control motor direction and speed. This chip handles all the motor and speed controls over I2C. Only two pins (SDA & SCL) are required to drive the multiple motors, and since it's I2C you can also connect any other I2C devices or HATs to the same pins.
In fact, you can even stack multiple Motor HATs, up to 32 of them, for controlling up to 64 stepper motors or 128 DC motors (or a mix of the two) - just remember to purchase and solder in a stacking header instead of the one we include.
Motors are controlled by TB6612 MOSFET drivers with 1.2A per channel and 3A peak current capability, a big improvement over L293D drivers and there are built-in flyback diodes as well.
We even had a little space so we added a polarity protection FET on the power pins and a bit of prototyping area. And the HAT is assembled and tested here at Adafruit so all you have to do is solder on the included 2x20 plain header and the terminal blocks.
Lets check out these specs again:
- 4 H-Bridges: TB6612 chipset provides 1.2A per bridge (3A peak) with thermal shutdown protection, internal kickback protection diodes. Can run motors on 4.5VDC to 13.5VDC.
- Up to 4 bi-directional DC motors with individual 8-bit speed selection (so, about 0.5% resolution)
- Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil, interleaved or micro-stepping.
- Big terminal block connectors to easily hook up wires (18-26AWG) and power
- Polarity protected 2-pin terminal block and jumper to connect external 5-12VDC power
- Works best with Raspberry Pi model A , B , Pi 2 B or Pi 3 B.
- Install the easy-to-use Python library, check out the examples and you're ready to go!
Comes with an assembled & tested HAT, terminal blocks, and 2x20 plain header. Some soldering is required to assemble the headers on. Stacking header not included.
Raspberry Pi, motors, and battery pack are not included but we have lots of motors in the shop and all our DC motors, and stepper motors work great. Check out Adafruit's detailed tutorial for tons of info including schematics, wiring diagrams, python libraries and example walkthroughs.
A gear motor is an all-in-one combination of a motor and gearbox. The addition of a gear head to a motor reduces the speed while increasing the torque output. The most important parameters in regards to gear motors are speed (rpm), torque (lb-in) and efficiency (%).
Micro DC Gear Motors are ideal for DIY enthusiasts and are designed to easily incorporate the encoder. These motors are inexpensive, small, easy to install, and ideally suited for use in a mobile robot car.
