Power Module with Dual internal Power Supply

mRo Power Zero - Step
This is a renewed high-quality power module standard based on the ACSP7 but with dual internal power supply to improve the stability of the hall-sensing.

The mRo Power Zero from mRobotics is designed especially for the Ardupilot community and it offers extremely accurate measurements across the entire current & voltage operating range with a non-invasive Hall-effect current sensor for UAV / Robotics application and high precision voltage dividing circuit for consistent and reliable measurements.

Compared to the ACSP7, the .5v offset is removed and the current sensing is compared with a dedicated power reference. The integrated electrolytic capacitor reduces voltage spikes which result from longer input cable lengths and higher voltage batteries.

Very nice and an option to add the following accessories might make it more attractive to some of us like:
XT90 plug also
FC cable in two different sizes (or more)
Enclosure

Hello, wouldn’t it be better to have a vendor dedicated section and leave the blog to interesting tech project stuff?

Probably hardware vendor section should be described as “support and marketing” so that all commercial stuff goes in there and doesn’t infest blog :slight_smile:

Any chance yo have a photo of the backside. I would love to see how the large power leads solder to the unit.

Hello Ricky, the size of the board is: 18mmx18mm (.70"x.70") Height: 7.30 mm (0.28")
It is practically almost the same as the back of the ACSP7
mRo Power Zero Back

Yes has a lot of space.

Hello Corrado_Steri, Yes, I mistakenly put it in that section. I will be more careful for future publications. Sorry for the inconvenience.
