Pololu item #: 705

This carrier board for ST’s VNH3SP30 motor driver IC operates from 5.5 to 16 V and can deliver a continuous 9 A (30 A peak). It offers built-in protection against reverse-voltage, over-voltage, under-voltage, over-temperature, and over-current and makes a great general-purpose motor driver.


Overview 
This module is a compact breakout board for ST’s high-power VNH2SP30 or VNH3SP30 motor driver IC, each of which is a fully integrated H-bridge that can be used for bidirectional speed control of a single brushed DC motor. The basic operation of the driver is summarized below, but we also recommend careful reading of the VNH2SP30 datasheet (283k pdf) or VNH3SP30 datasheet (228k pdf) before using this product. The board incorporates most of the components of the typical application diagram on page 8 of the VNH2SP30 datasheet, including pull-up and current-limiting resistors and a FET for reverse battery protection. It ships fully populated with its SMD components, including the VNH2SP30 or VNHSP30 motor driver IC, as shown in the product picture.

General specifications

  • Motor driver:  VNH3SP30 
  • Motor channels:  1 
  • Minimum operating voltage:  5.5 V 
  • Maximum operating voltage:  16 V1 
  • Continuous output current per channel:  9 A 
  • Peak output current per channel:  30 A 
  • Maximum PWM frequency:  10 kHz 
  • Reverse voltage protection?:  Y 

Real-world power dissipation considerations
The motor drivers have maximum current ratings of 30 A continuous. However, the chips by themselves will overheat at lower currents (see table above for typical values). The actual current you can deliver will depend on how well you can keep the motor driver cool. The carrier printed circuit board is designed to draw heat out of the motor driver chips, but performance can be improved by adding a heat sink. In our tests, we were able to deliver short durations (on the order of milliseconds) of 30 A and several seconds of 20 A without overheating. At 6 A, the chip gets just barely noticeably warm to the touch. For high-current installations, the motor and power supply wires should also be soldered directly instead of going through the supplied terminal blocks, which are rated for up to 15 A.

Many motor controllers or speed controllers can have peak current ratings that are substantially higher than the continuous current rating; this is not the case with these motor drivers, which have a 30 A continuous rating and a over-current protection that can kick in as low as 30 A (45 A typical). Therefore, the stall current of your motor should not be more than 30 A. (Even if you expect to run at a much lower average current, the motor can still draw high currents when it is starting or if you use low duty cycle PWM to keep the average current down.)

Reverse-battery protection
The motor driver boards include an N-channel MOSFET for reverse-battery protection. This component keeps the motor driver from destroying itself if the input power is accidentally connected backwards. However, this component does slightly increase the total resistance between your battery and your motor. For slightly improved performance, the MOSFET can be bypassed by connecting the negative battery terminal to the bypass pin. (This terminal will also need to be connected to your logic supply ground.)

Easy tasty way to support digestive health
PSA- You need more fiber. I've been using these prebiotic fiber gummies for a while now, and overall I've had a very positive experience. The Citrus Berry Splash flavor is genuinely enjoyable, which makes them much easier to take consistently than some other fiber supplements I've tried. I also love the convenience I keep the bottle on my coffee table and have them after dinner when I watch TV. I've noticed that they help support regularity when taken consistently, and I like knowing that they contain prebiotic fiber to help nourish beneficial gut bacteria. For me, these gummies work best as part of an ongoing digestive health routine rather than as a quick solution when I'm already feeling backed up. In those situations, I personally find fiber powders to be a bit more effective. However, that's not really the purpose of these gummies—they're designed to help maintain digestive health and regularity over time, and I think they do that well. The gummies tend to stick together in the bottle, especially once I've gotten about halfway through it. I've found that storing the bottle upside down helps prevent them from clumping too much and makes them easier to grab. Overall, these are a great option if you're looking for a tasty, convenient fiber supplement that's easy to stick with long term. They've helped me maintain regularity, taste great, and are much easier to incorporate into a busy schedule than many other fiber products. I would definitely purchase them again.

Delicious and easy to chew probiotic gummies that also add fiber to your diet!
i just received this package of probiotic fiber gummies and can assure you that they taste terrific! The container is easy to open and includes an internal seal both to assure freshness and the safety of the product. These are individual gummies that are easy to chew and taste yummy! One flavor is citrusy and another has a berry flavor. Chewing them was not at all difficult and I did not feel like I ended up with lots of residual product stuck in my teeth. Each serving of 3 gummies provides 6 grams of fiber which is an additional benefit to the probiotics! The recommended dose is 3-6 gummies per day. As well as being flavorful and easy to chew, the addition of fiber is a great benefit for most people’s diets! I am a healthy woman of “a certain age” as the French say. I don’t have specific health problems that I know of but I am trying in general to maintain a healthy lifestyle. That was my goal in acquiring this product. This is the first day I have eaten and enjoyed these probiotic gummies. Of course I have not experienced any health benefits yet but my initial experience eating these soft gummies has been extremely positive! If you are interested in adding probiotics or fiber to your diet, I encourage you to purchase these inexpensive, delicious and easy to chew gummies!

Tastes Great!
I’ve tried a lot of fiber supplements over the years, and these are honestly one of the easiest ones to stick with consistently. The biggest thing for me is that they actually taste good. The Citrus Berry Splash flavor is pleasant without being overly sweet or having that weird artificial vitamin aftertaste some gummies have. They’re soft and easy to chew too. Some fiber gummies can be oddly hard or stick to your teeth, but these have a good texture and are easy to take daily. What I really appreciate is the convenience. It’s so much easier for me to remember gummies than mixing powders into drinks all the time. I can just take them quickly in the morning or after dinner and be done with it. After using them consistently, I’ve noticed they help keep things more regular without feeling harsh or causing the kind of stomach discomfort some fiber products can. They feel gentler compared to a lot of other options I’ve tried. The large bottle is another plus. With 126 gummies, it lasts quite a while, so even though the upfront cost might seem a little high, I think the value is pretty reasonable for how long they last. I also like that they’re a simple way to add a little extra support to my routine, especially on days where my diet probably isn’t perfect. Overall, easy to take, good flavor, gentle on the stomach, and something I’ll continue buying.

Yummy and great alternative!
I’m a regular user of Benefiber powder. I add it to my protein shakes in the morning - but there are days I don’t have time to make a shake. I needed an alternative source for fiber and decided to try these. PROS: - Tasty! I really like the fruity flavor. It’s not too strong of a flavor and it leaves a decent aftertaste. - They’re easy to chew, swallow, and go down. - Container comes with 126 gummies which will definitely last a while. - Freshness is good. I’ve opened and shut the container several times over the last couple of weeks and the remaining gummies stay soft. - They work to keep me regular, which is nice because I don’t always have to have the powder. CONS: - They make my husband gassy and bloated. He isn’t used to daily fiber, so maybe it’s just going to take some getting used to.

Great flavor, great value!
I was truly impressed with these chewable vitamins! First, they have a delightful flavor, possibly a mix of orange and raspberry, and they taste pleasantly sweet. The texture resembles that of fruit snacks rather than gummies, as they did stick to my teeth slightly, but not for long. You receive a good supply of 42 servings (with 3 chewables per serving). I did find that they contain a bit more sugar than I expected (2g), and I wish they included at least some amount of soluble fiber. However, with 6g of dietary fiber, they complement my usual supplement well. Overall, this is a great value for the money and an impressive supplement.
