Reference
See Intel NUC Board D54250WYB and Intel NUC Board D34010WYB Technical Product Specification Order number H18263-006.
Power Requirements
See page 45 of the above spec. The power requirements are:
- +12-19 volts
- The plug is a 5.5 mm/OD and 2.5 mm/ID.
These are ballpark readings needed to determine estimate supply power requirements. Load was measured under the following conditions. The readings were taken from a current meter using a bench power supply. Current load changes continuously as the Linux processing requirements change. Consider the follow on the low end with peaks at lease 25% higher. All measurements are of low accuracy because the change quickly and were eyeballed.
The following were taken with: keyboard, mouse, wireless, wired, and HTMI monitor.
| Activity | Impact (amps) |
|---|---|
| Boot to desktop | 1.0+ intermittently |
| Steady state in desktop | 0.34 to 0.43+ |
| Active use of USB webcam | added 0.15 |
| Inactive motor controller | added 0.04 |
| Camshift rotate demo driving wheels (no load) | 0.57 to 0.66 + |
This test is designed to determine the impact of supply voltage on current requirements.
| Supply voltage | Current (amps) | Watts |
|---|---|---|
| 18 | 0.55 + | 9.9 |
| 15 | 0.65 + | 9.8 |
| 12 | 0.85 + | 10.2 |
The steady state power requirements are roughly 10 to 13 watts a independent of supply voltage. A supply that delivers 2A and 18V should provide the required headroom for intermitent spikes.
