Hobbywing 5V 3A UBEC Step-Down Converter (Hobbywing power converter)

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
  • Input: 5.5V - 26V (2 - 6 cells lithium battery pack or 5 - 18 cells NiMH /NiCd battery)
  • Size: 43mm*17mm*7mm (L*W*H)
  • Weight: 11g

Adafruit TB6612 1.2A DC/Stepper Motor Driver Breakout Board (Adaf TB6612 stepper driver)
Description:

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"
  • Weight: 1.8g



What's in the box?:

Flexible Shaft Coupling OD18mmx25mm CNC Stepper Motor Coupler ID5x5mm (Flexible Shaft Coupling 5x5mm)
Description:

Flexible couplings connect two shafts, end-to-end and in the same line, causing both to rotate at the same speed. They also flex to compensate for misalignment and movement between shafts.

Shaft misalignment can limit a machine’s performance, cause excessive vibration, high reaction loads, and accelerated wear, and often leads to premature equipment failure. Flexible Shaft Couplings can help prevent these issues by transmitting torque while compensating for parallel, angular, and axial misalignment between drive components. When installed correctly, flexible shaft couplings can also reduce vibration, minimize noise, and protect driveshaft components. 

Specification: 

  • Material:Aluminum(LY12)
  • Outside diameter:D=18mm

Adafruit DC & Stepper Motor HAT - Mini Kit (Adafr DC and Step Mini Kit)
Description:

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 capabilitya 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.
