2020.12 Servo Hat Test
Raw
2020.12 servo hat test
Servo hat from Cytron.io
Input voltage at screw terminals to test voltage available at A) servo power rail and B) raspi 5v pins
In(v) Out (v)
5.90 0.01
6.00 5.2~5.1 fluctuating
6.10 5.2v
6.50 5.1v
11.90 5.1v
above 12 - did not test
Voltage on raspi "5v pins" are always equal to the red servo pins (middle pin) so it is expected those are shared.
Can power the raspberry pi using 6.1v and higher.
Current: did not test output current capability.
Test continuity:
Mounted onto raspi 4, the Ground pins are in common:
* pi rail
* input terminal of hat
* ground of servo rail
power pins in common:
* pi rail 5v pins
* power pins of servo rail
