Power Specification #22

Closed LFrancis23 closed 2 years ago

LFrancis23 commented 2 years ago

We need to power the entire project off the Brainboard PCB, and take power efficiency measurements. Make sure measurements are made only when the BrainBoard is connected to the Keysboard operating in Auto-2 mode, with the Display on.

Measurements will be made with two multimeters on either end of the power circuit. They will each measure the current, and then two oscilloscope probes will monitor voltage. Use the following equation for efficiency: ((Vout*Iout)/(Vin*Iin))*100

We must be at least 75% efficient.

Power Specification Met, all measurements above 85% efficiency, only 75% required.
