Support » Pololu Dual VNH5019 Motor Driver Shield User’s Guide » 3. Getting Started with an Arduino »
The following tools and components are required for getting started using this motor driver as an Arduino shield:
* Note for Due users: The voltage on the current sense pins will exceed the Due’s 3.3 V limit when the current draw exceeds ~23 A. The Due should generally be able to handle this since the MCU’s integrated protection diodes will clamp the input voltage to a safe value (and since the CS circuit has a 10 kΩ resistor in series with the output, only a few hundred microamps at most will flow through that diode). However, if you really want to be safe, you can use a 3.3 V zener diode to clamp the current sense output voltage to a maximum of ~3.3 V. If you want to get the full range of current feedback while using the Due, you can disconnect the shield’s current sense pins from the Due and then reconnect them through a voltage divider; see Section 6.a for more information.
