Both the top and bottom sides of the PCB have large heat spreading areas connected by thermal vias to act as an effective heat sink for the two DRV8801 devices.

Careful design: the Rugged Motor Driver is carefully designed for high heat transfer away from the DRV8801 devices, keeping them cooler at higher currents. 
DMOS construction: the DRV8801 uses modern MOSFET switches in the H-bridge rather than the older BJT technology in the L298, leading to lower power losses. 
This means that the power dissipation is spread out over two devices and over a wider area of the PCB rather than all being dissipated in one place.
Dual drivers: the Rugged Motor Driver uses two DRV8801 H-bridge IC’s, one for each motor output, rather than a single L298 for both outputs. Why does the Rugged Motor Driver deliver twice as much total current as the Ardumoto? With aggressive heatsinking, forced-air cooling, or other active cooling approaches it is possible that the L298 will provide 2A of current, and it is possible that the DRV8801 will provide 2.8A of current. The “2A” number often associated with the L298 means that as long as no other datasheet maximums are exceeded, the driver will provide 2A of current, but as you can see from our experiment this cannot be done without first exceeding the maximum temperature. But each datasheet parameter is often specified by itself, without consideration for other constraints. There is an aspect of marketing involved here - manufacturers like to put the largest possible number in their documentation to lure prospective buyers.

Why can’t the motor drivers achieve the “maximum current rating” listed on the datasheet? Example 3: Write a Forward () method using L298N motor driver. Step 2: Connect the L298N motor driver to Arduino.
The Rugged Motor Driver delivered twice as much total current as the L298-based motor driver Example 2: Translating the L293D Truth Table. Due to thermal shutdown, neither motor driver delivered the “maximum current rating” listed on the H-bridge device datasheet.
