Description
Dual VNH2SP30 Motor Driver Carrier MD03APololu item #: 708 The Pololu dual high power motor drivers are compact carriers for the VNH3SP30 and VNH2SP30 motor driver integrated circuits from ST. 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. (The current sense circuit is populated on both versions of the board, but only the VNH2SP30
Pololu item #: 708
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 drivers 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.
This product can get hot enough to burn you long before the chip overheats. Take care when handling this product and other components connected to it.
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 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.)

I guess the smell is offputting
Size: 2-pack, Style: Duo
My dog loves chocolate stuff. But for some reason, wasn’t a huge fan of these balls. She played with them a little bit, but they’re not her favorite.

Durable
Pattern Name: Detachable high wall
Much better then just using pads, and they can’t chew the pads.

Great pee pad holder
Pattern Name: Detachable high wall
This pee pad holder has made me and my pup’s life so much easier! It’s light, easy to clean, and works well with my pup! It’s a lifesaver when it’s really cold and rainy outside for my pup to have a dry place to go potty. Would recommend to all dog owners, especially those in apartments with small spaces.

Great
Pattern Name: Detachable high wall
Great quality, easy to clean, fit well the standard pee pad (24x24). Hopefully I can get my dog well trained to not have any accidents.

A Game Changer for Puppy Training!
Pattern Name: Detachable high wall
I recently purchased the PAWISE Dog Pee Pad Holder Tray with Splash Guard, and I have to say, it has made a significant difference in our puppy training routine!
First off, the size is perfect for my small to medium-sized dog. The 23.6-inch tray provides ample space for the puppy pads, and I've found that it holds them securely in place — no more slipping or sliding around, which is a major plus! The detachable high wall is a great feature, as it helps contain any messes or spills, keeping my floors clean. The splash guard really works; we had some initial worries about our puppy being a bit of a scatterer during pee time, but this tray has nearly eliminated those issues.
Cleaning it is a breeze. The tray is easy to wipe down, and since it’s designed to keep everything contained, I don’t have to spend a long time cleaning up after accidents. I also appreciate the durable material—it's clear that it's built to last.
One thing I didn't expect was how much my puppy took to it. He seemed to understand what it was for right away, which made the whole potty training process less stressful for both of us. The high-wall design gives him a sense of enclosure that I think he finds comforting.
Overall, I would highly recommend the PAWISE Dog Pee Pad Holder Tray for anyone who's in the midst of puppy training. It’s functional, easy to clean, and has made our indoor potty routine much more manageable. This product is definitely worth the investment!
