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 estimate supply power requirements. Loads readings were taken from a current meter on a bench power supply. Load changes continuously as 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 readings were eyeballed.
The following were taken with a keyboard, mouse, wireless, wired, and HTMI monitor active.
Activity | Impact (amps) |
---|---|
Boot to desktop | 0.3 with 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. Measurements were taken with an active system - Camshaft demo.
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.
