Operating and Storage Temperature Conditions

Table 1. Operating and Storage Temperatures and Humidity Condition
Specification	Condition
Operating temperature	0°C to 35°C (maximum at continuous operation)¹
Storage temperature	0°C to 70°C
Operating humidity, non-condensing	8% to 90%, and a dew point of –12°C
Storage humidity, non-condensing	5% to 95%
The Kria KD240 Drives Starter Kit is for evaluation purposes only. The operating temperature range is not fully tested, it is a general guideline. Use the Kria KD240 Drives Starter Kit in a typical lab environment. Do not operate beyond room temperature.

KD240 Starter Kit Cooling Solution

The KD240 Starter Kit uses a passive cooling solution to support the maximum 6.5W base K24 SOM thermal power dissipation at 35°C ambient temperature. Variable fan speed control can be implemented through an FPGA-based PWM fan controller. The fan gating signal is connected to an FPGA HD I/O bank pin for control. Consult the corresponding KD240 Starter Kit carrier card schematic for the specific pin assignment. Refer to Kria SOM Wiki for the latest thermal solution options.
