all development boards, why would you not want to keep your board safe and sound inside this clear plastic enclosure? These cases protect your Arduino Uno from things like rogue wires that might short it out while still allowing full access to the board! Simply snap the Uno into the bottom half of the enclosure, then snap the two sides together. As you may have noticed, these enclosures are actually transparent. The enclosures are perfect for letting you see your Arduino Uno and make any needed adjustments easily. The enclosure provides slots to access each header, USB port, power jack, the reset button, the AREF and ICSP connectors, as well as feet and vents to ensure the board gets proper cooling and slide-in wall mounting slots. All of the status LEDs on the Uno are visible through the case thanks to light pipes embedded in the design. This is a really durable case that will do a great job protecting your Arduino Uno! Dimensions: 7.8 x 6.1 x 2.1cm <<

Arduino library make it easy to control a pair of bidirectional, brushed DC motors with an Arduino or Arduino clone. The board features Allegro_s A4990 dual H-bridge motor driver IC, which operates from 6 V to 32 V. It can deliver a continuous 0.65 A to each motor channel, and the current control feature of the A4990 limits the peak motor current to about 0.9 A per channel with the onboard sense resistors, making this shield well suited for low-current, high-voltage motors.
The shield ships fully populated with its SMD components, including the A4990 driver and a FET for reverse battery protection, header pins for interfacing with an Arduino and terminal blocks for connecting motors and power are included but are not soldered in (see the Assembly with included hardware section below).
The shield uses digital pins 6, 7, 8, 9, and 10 for its diagnostic and control lines. It should be compatible with any board that has a standard Arduino pin arrangement and the ability to generate PWM signals on pins 9 and 10, such as an Arduino Uno, Leonardo, Due, or Mega 2560.
This shield is intended to provide a low-cost, basic motor driver option for Arduinos, so it is much smaller than typical Arduino shields and does not include pass-through, stackable headers. For higher-power drivers with more configuration options, see our larger MC33926 and VNH5019 motor driver shields.
For a lower-voltage, higher-current alternative to this shield, please consider the DRV8835 dual motor driver shield. We also have a smaller A4990 carrier for those using something other than an Arduino or with tighter space constraints. Features
- Dual-H-bridge motor driver: can drive two DC motors or one bipolar stepper motor
- Motor supply voltage: 6 V to 32 V
- Logic supply voltage 2.5 V to 5.5 V Output current: 0.65 A continuous per motor
- Current control limits peak current to 0.9 A per motor
- Can work with ultrasonic (> 20 kHz) PWM frequencies, which allows for quieter motor operation
- Shield can optionally power the Arduino base directly when motor supply voltage is suitable
Arduino library makes it easy to get started using this board as a motor driver shield
Robust:
- Reverse-voltage protection on the motor power supply
- Can survive input voltages up to 40 V
- Under-voltage and over-voltage protection
- Over-temperature protection
- Short-to-supply, short-to-ground, and shorted-load protection on the motor outputs <<

of electronics. Its great for connecting things together, soldering to perf-boards or PCBs to allow 22AWG wire or male header to connect, etc. We go through these gals real fast, and thought that given how handy they are, we'd offer them in a pack of five! Each pack contains 5 x dual row female 36-pin long headers, 0.1' pitch, that can be stacked next to each other on a 0.1' grid. They aren't 'break-away' style but can be cut manually with diagonal cutters or thin hacksaw - we suggest to sacrifice one socket connector by cutting in the middle of it. They're even gold plated so they wont oxidize! <<

отверстий позволяют надежно закрепить мотор на скобе, а три отверстия с резьбой М3 в основании предназначены для установки скобы на шасси. В комплект входит 9 винтов М3. Расстояние между центрами отверстий в основании скобы 14.8 мм.This machined aluminum gearmotor bracket lets you securely mount Pololu_s 37D mm metal gearmotors to your project. The six holes on the bracket face line up with the six mounting holes on the 37D gearbox, and the bracket features three tapped M3 holes on the bottom that can be used to mount it to a surface. The bracket includes nine M3 screws: three for mounting the bracket to a surface and six for mounting it to the gearmotor.This light and sturdy bracket is specifically designed for Pololu_s 37D mm metal gearmotors. Nine 8 mm M3 screws are included for securing the motor to the bracket and the bracket to a surface. The bracket features three tapped M3 holes along the bottom (spaced 14.8 mm, or 0.58?, apart) that are used to mount it to another object.We also carry a stamped L-bracket for our 37D mm gearmotors that provides alternate mounting options, but the stamped bracket is not quite as sturdy as this machined bracket and can bend under heavy load. <<

high voltage, high current, 4-channel driver.
Basically this means using this chip you can use DC motors and power supplies of up to 25 Volts, thats some pretty big motors and the chip can supply a maximum current of 600mA per channel, the L293D chip is also what's known as a type of H-Bridge.
The H-Bridge is typically an electrical circuit that enables a voltage to be applied across a load in either direction to an output, e.g. motor.
2 interface for 5V Servo connected to the Arduino's high-resolution dedicated timer - no jitter.
Can drive 4 DC motors or 2 stepper motors or 2 Servo.
Up to 4 bi-directional DC motors with individual 8-bit speed selection.
Up to 2 stepper motors (unipolar or bipolar) with single coil, double coil or interleaved stepping.

Подключение пять вольт через нагревательный (H) контактами удерживает датчик достаточно горячей, чтобы функционировать правильно. Подключение пять вольт либо в А или В контактами вызывает датчик, чтобы излучать аналоговое напряжение на другие выводы.
