The Motoron M2S18v20 Dual High-Power Motor Controller Shield for Arduino makes it easy to control two high-power DC motors from an Arduino or Arduino-compatible board through an I²C interface. The M2S18v20 supports motor supply voltages from 6.5 V to 30 V and can deliver continuous output currents up to 20 A per motor. This version ships with soldered stackable headers and terminal blocks. Stacking disclaimer: The included terminal blocks are taller than the headers, so this version is intended to be used by itself or at the top of a stack. For stackable shields, we recommend getting the kit version and soldering wires to the board instead of the terminal blocks.
