Cooling

Natural convection; no fan or heatsink is fitted

The board carries no high-power stages — the motor drives are external — so dissipation is low and dominated by the step-down regulator. Mount the unit so that air can move over the enclosure, and avoid placing it directly above a significant heat source. No derating of the I/O ratings is required within the operating temperature range.
