Pololu Wheel 90 mm × 10 mm – Black

These black plastic wheels have silicone tires and measure 90 mm (3.54 inches) in diameter, and they press-fit onto the 3mm D shafts on many of our motors, including our micro metal gearmotors and our mini plastic gearmotors. Additionally, this wheel is compatible with several of our universal mounting hubs, which can serve as adapters for motors with different shafts. Six mounting holes for #4 or M3 screws make it possible to use the wheel with any of our universal mounting hubs for those screw sizes, enabling these wheels to be used with our larger metal gearmotors and stepper motors. The included silicone tires, which feature horizontal treads for improved traction.

Pololu Ball Caster with 1 Inch Plastic Ball and Ball Bearings

This ball caster uses a 1 inch diameter plastic ball and has an overall height of 1.1 inches (29 mm). The two-part housing snaps together to securely enclose the ball and three ball bearings that minimize friction between the ball and the ABS housing.

This ball caster kit includes a two-part black ABS housing, a 1 inch diameter POM plastic ball, three 3 mm × 7 mm × 3 mm ball bearings, and three dowel pins used to hold the ball bearings. When assembled, the ball caster is capable of rolling in any direction with low friction, making it suitable for use as a third contact point for wheeled, differential-drive robots weighing up to around ten pounds.

The base piece of the housing has holes for three mounting screws and slots for ball bearings. The second part of the housing snaps into the base piece to secure the ball and ball bearings. The assembled ball caster has an overall height of 1.1 inches (29 mm).

Perforated Phenolic Plate

So you finish your electronics projects, such as printed circuits. We know that designing a prototype or electronic project can be a complicated task if you do not have the necessary items to carry it out, so with us you it a phenolic plates of a face, two sided or perforated, ferric chloride, auto-adherable tracks, leaves thermal transfer or permanent ink markers so that your circuits are perfect.

Steren Model 155

Bakelite phenolic plate with copper, 4.5 cm x 4.5 cm, engraved and perforated with 164 orifices for components and 4 for fixing the plate. Ideal for projects or prototypes.

USB/DC Lithium Polymer Battery Charger 5-12V – 3.7/4.2v Cells

Charge your single-cell lithium ion/polymer battery any which way you like with this board. Other nice things about this charger include multiple LEDs for power & charging status, including a charging LED which will blink when the battery is full. If the charger gets too hot from high-speed charging, it will slow down the charge rate automatically. You can easily adjust the charge rate up to 1.2A or down to 100mA. For use with Adafruit Lipoly/LiIon batteries only. Other batteries may have different voltage, chemistry, polarity or pinout.

  • Use USB or DC power – 5 to 12V input
  • Charges one single-cell 3.7/4.2v batteries with constant current/constant voltage
  • Three indicator LEDs – green for Power, orange for charging and red for error
  • Charging LED will blink when the battery is full
  • 2 JST connections so you can keep the battery plugged in and powering your project
  • Terminal block connections galore just solder in 3.5mm terminal blocks
  • Default charge rate is about 500mA, but you can easily change this by soldering in a through-hole resistor on. The chip can do 100-1200 mA charging
  • Safety timer will stop charging after about 14 hours
  • The chip supports a standard 10K thermistor, which we have stuffed as a standard resistor. You can solder in a thermistor easily

LiPower Boost Converter

The LiPower board is based on the incredibly versatile TPS61200 boost converter. The board is configured to be used with a LiPo battery, has solder jumper selectable 5V and 3.3V output, and an under voltage protection of 2.6V. However, the board can also be used as a general purpose buck and boost regulator with an input voltage as low as 0.3V. With such a low input voltage and quiescent current, the board also works well in energy harvesting applications that use low input voltages.

XBee Explorer Regulated

The XBee Explorer Regulated takes care of the 3.3V regulation, signal conditioning, and basic activity indicators. It translates the 5V serial signals to 3.3V so that you can connect a 5V system to any XBee module. The board was conveniently designed to mate directly with Arduino Pro boards for wireless bootloading and USB based configuration. This unit works with all XBee modules including the Series 1 and Series 2.5, standard and Pro versions. Plug an XBee into this breakout and you will have direct access to the serial and programming pins on the XBee unit and will be able to power the XBee with 5V.

DC Motor

A DC motor is any of a class of rotary electrical motors that converts direct current electrical energy into mechanical energy. The most common types rely on the forces produced by magnetic fields. Nearly all types of DC motors have some internal mechanism, either electromechanical or electronic, to periodically change the direction of current in part of the motor.

DC motors were the first form of motor widely used, as they could be powered from existing direct-current lighting power distribution systems. A DC motor’s speed can be controlled over a wide range, using either a variable supply voltage or by changing the strength of current in its field windings. Small DC motors are used in tools, toys, and appliances. The universal motor can operate on direct current but is a lightweight brushed motor used for portable power tools and appliances. Larger DC motors are currently used in propulsion of electric vehicles, elevator and hoists, and in drives for steel rolling mills. The advent of power electronics has made replacement of DC motors with AC motors possible in many applications.

DRV8835 Dual Motor Driver Carrier

This tiny breakout board for TI’s DRV8835 dual motor driver can deliver 1.2 A per channel continuously (1.5 A peak) to a pair of DC motors, and it supports two possible control interfaces for added flexibility of use: IN/IN and PHASE/ENABLE. With an operating voltage range from 0 V to 11 V and built-in protection against reverse-voltage, under-voltage, over-current, and over-temperature, this driver is a great solution for powering up to two small, low-voltage motors. The carrier board has the form factor of a 14-pin DIP package, which makes it easy to use with standard solderless breadboards and 0.1 inch perfboards.

Solarbotics RM2 (High-Power Motor for GM2/3/8/9)

This high-power brushed DC motor fits in the GM2/3/8/9 series of gear motors, offering approximately 3 times the speed, twice the torque and quadruple the power-draw. Retrofitting the gear motor is easy – just remove the motor retainer strap, transfer the pinion gear, and reinstall – that’s it.

Stepper Motor

A stepper motor, also known as step motor or stepping motor, is a brushless DC electric motor that divides a full rotation into a number of equal steps. The motor’s position can be commanded to move and hold at one of these steps without any position sensor for feedback, as long as the motor is correctly sized to the application in respect to torque and speed. Switched reluctance motors are very large stepping motors with a reduced pole count, and generally are closed-loop commutated.

EasyDriver – Stepper Motor Driver

The EasyDriver is a simple to use stepper motor driver, compatible with anything that can output a digital 0 to 5V pulse. The EasyDriver requires a 6V to 30V supply to power the motor and can power any voltage of stepper motor. The EasyDriver has an on board voltage regulator for the digital interface that can be set to 5V. Connect a 4-wire stepper motor and a microcontroller and you’ve got precision motor control! EasyDriver drives bi-polar motors, and motors wired as bi-polar.

Joystick

A joystick is an input device consisting of a stick that pivots on a base and reports its angle or direction to the device it is controlling. A joystick, also known as the control column, is the principal control device in the cockpit of many civilian and military aircraft, either as a centre stick or side-stick. It often has supplementary switches to control various aspects of the aircraft’s flight.

Pololu Adjustable Step-Up Voltage Regulator U1V11A

This compact U1V11A switching step-up voltage regulator efficiently boosts input voltages as low as 0.5 V to an adjustable output voltage between 2 V and 5.25 V. Unlike most boost regulators, the U1V11A offers a true shutdown option that turns off power to the load, and it automatically switches to a linear down-regulation mode when the input voltage exceeds the output.
