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.

UBEC's (Universal Battery Eliminator Circuit's) are simply DC to DC step down voltage regulators! This UBEC is perfect for the Raspberry Pi, as it's able to take high voltages (5.5V up to 26V), and outputs a consistent safe voltage of 5V at up to 3A nominal or 5A max! The Hobbywing 5V 3A UBEC is a switch-mode type, which results in it being much more efficient than linear type UBEC's (so your batteries will last longer!)
UBEC's are perfect for applications where you plan to use the Raspberry Pi in a circuit with high voltages such as robots where you'll be driving motors!
Due to the voltage drop caused by the Raspberry Pi, it is recommended to input a minimum of 6.5V to receive a stable 5V output. Anything lower than 6.5V will result in a low voltage warning on the Pi.
Please Note. The Hobbywing UBEC can be set to output either 5V or 6V using an onboard jumper select! Please DOUBLE CHECK your output voltage is correct before connecting your microcontroller or circuit!
Features
- Designed with an advanced switch mode DC-DC regulator IC.
- Battery polarity reversal protection.
- A metal shield covers almost all the electronic components, and a specially made filter is attached to the output wires to significantly reduce the electromagnetic interference.
- The working status is shown by an indicator (LED), which lights when the output is in normal range.
- Output Voltage: [email protected] or [email protected] (Changeable with an output-voltage select jumper)
- Continuous output current: 3 Amps
- Maximum output current: 5 Amps

1 x DC 9V Battery Button Power Cable
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!
Specifications:
- Current Limit: 1.2A
- Size: 27mm x 19mm x 3mm / 1.1" x 0.7" x 0.1"

Specifications:
This waterproof ultrasonic distance sensor is for those applications that are a bit more rugged! 25cm - 450cm sensing range.
We have used the HC-SR04 Ultrasonic Distance Sensor many times and for many good reasons. It is pretty easy to use, it performs well, and it is very inexpensive. For collision avoidance robots or intruder detection, this sensor is usually all you’ll need.
However, using the HC-SR04 outside is a different story. It is a pretty fragile device and can easily be damaged by dirt, or even high winds. And, above all, it is not waterproof.
For these circumstances you can use this sensor, in more weathered states, even outdoors
