2.2.1 Common Connectors and Headers Across all EVM Variants

Figure 2-1 shows a larger view of the DRV824x-Q1EVM. Because the DRV814x-Q1EVM shares much of the same design, only the DRV824x-Q1EVM is referenced.

The micro-USB connection at the top of the EVM is used for GUI communications, and MCU firmware updates. Main supply input A supply voltage ranging from +4.5 VDC to +36 VDC from a battery or a DC voltage source is connected to the large screw thermal block (fused and reverse polarity protection).

Connect the bi-directional brushed-DC motors to the OUT1 and OUT2 banana jacks. Ground and VM supply connections are provided as a convenience for high-side or low-side switched loads (for example, unidirectional brushed DC motor or solenoid).

Note: VM has a small voltage drop with respect to the main supply due to the N-channel MOSFET in the reverse protection circuit.
