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.)

Great dog toys
Color: Orange & Blue
These Zeaxuie octopus dog toys are a huge hit with my pup! The crinkle and squeaky features immediately grabbed his attention, and he’s been happily chewing and playing with them ever since. I love that they’re stuffing-free, so I don’t have to worry about any mess. They’re the perfect size for small to medium breeds and seem very durable. These toys have kept my dog entertained for hours – definitely a great purchase!

Our dogs love these
Color: Orange & Blue
We have two rough collies that love to play fetch, tug, and ragdoll. We decided to add these to their play toys. Since getting them they have been ignoring their ducks and going straight for the octopus. We just got them so can’t say much about durability yet but they have been playing with them for hours and still look brand new. Love giving our dogs choices so we can ask them for certain animals to fetch. Love the non-stuffing and the crinkle.

Not for Aggressive Chewers
Color: Orange & Blue
My Dog Loves them. He immediately took the squeaker out, and dismantled some of the legs, but he still runs around trying to play tug-of-war and fetch with the dismembered body piece's 😂☺️

Didn't even last an hour!
Color: Orange & Blue, Color: Orange & Blue
I had high hopes for these toys as the description sounded like they might be not easily destructible. Well, I was dissapointed again. Our shih-poo (half shih-tzu/ half minature poodle) had one of the toys apart in an hour. See photo.
