Wafer-level: 1. Up to 4 bidirectional DC motors with individual 8-bit speed selection (thus, approximately 0.5% resolution) 2. Up to 2 stepper motors with single-coil, dual-coil, interleaved, or microstepping (unipolar or bipolar). 3. Motors automatically disabled at power-on 4. Large terminal block connectors for easy connection of wires (18-26 AWG) and power supply 5. Arduino reset button pops out from the top 6. 2-pin terminal block with polarity protection and jumper wires for connecting an external power supply for separate logic/motor power supply 7. Includes pre-assembled and tested shielding, terminal blocks, standard plugs, and jumper wires. Some soldering is required to assemble the connectors. Stacking connectors are not included, but we sell them in our store, so if you plan to stack the shielding, be sure to pick them up as well. Arduino and motor are not included. However, we have a wide selection of motors in our store, including all our hobby servos, DC motors, and stepper motors, which are all reliable and easy to use.
