After I had a few problems with the standard power module from 3DR and the ones from Hobbyking, like falling off resistors (overheated) and burned out BEC from voltage spikes, I finally designed my own PM modules. The sensor boards are compatible to Pixhawk, APM, Pixhawk lite, AUAV-X2, DroTek und CUAV Pixhack.
These modules are based on a true hall current sensor, so heat is no more an issue !!!
The sensors boards are able for continuous current of 100A for HS-100-V2 and 200A for HS-200-V2 (no time limit), the maximum over current is 1200A@25'C and 800A@85'C for 1 second.
Here some details:
The Sensor board is installed only into the positive main battery wire and the BEC should be installed as close as possible to the battery connector.
Quality control of the finished product:
To post here all the quality control during the production would be a very long story, so all I can say is, that it is carried out and recorded.
The final QC before the boards are shipped, is a setup with an FC (Pixhawk) and connected to MissionPlanner to check the calibration values for current and voltage measurement.
This final test result will be passed to the customer together with the order confirmation and shipment tracking number by e-mail.
REM: Which power module supplier out there actually use the PM to power up a real FC before shipment ?
So I hope everybody understands, that if I say "safety first"... then I mean it.
Why Hall sensor ?
Why only a few supplier use a true hall sensor for current measurement in an MR ?
Why output voltage to Pixhawk /APM is 5.35V and not 5.0V ?
Why the cable from UBEC to the sensor board is 4 pol ?
Why sensor board and UBEC are separated ?
Why is there an additional capacitor installed at the input of the UBEC ?
How can I get one of these boards ?
Got mine yesterday, thx for fast delivery to Germany, like the sticker and the extra shrink tube.:-)
Congrats, nice Power Module !
New available for the current sensor HS-100-V2 and HS-200-V2, is now an Hybrid BEC (Switching power supply with linear LDO in series) for 4-14S LiPo.

Together with HS-200-V2...
You can find a new voltage & current sensor board here
This module can measure the battery voltage and current consumption with effect Hall sensor. It's compatible with Dropix and Pixhawk flight controller!
Have you a wiki to describe how to connect your board to a Pixhawk please?
I have just uploaded new picture on the page of product. Check please.
@ Drotek... it is quite an insolence, that you post your product here in other peoples product page. Did you don't have enough courage to open you own thread ?
Normally I don't comment on other peoples design, but since you post it here, it looks like you're begging me for it.
I might not cover all issues with the board, as you don't present too much details, but the flaws I can see so far, does makes me afraid of using such sensor board. Even the nice label "Made In France" or the gold plated PCB (which is to some point useless) do not make it up.
Please do not reply to my comment... just open your own thread and I wish you many unhappy/happy customers.
Notes so stupid and baseless. We see that electronics is a mystery for you. Ahhhh !!
All mentioned points are sadly unfounded.
At least you made us laugh. Keep the bad work. Thank you.
Well that's Drotek on my 'never ever buy from' list. Good job Christian on your interesting products.
Hi Drotek, you shot yourself in the foot for not arguing what makes your product different to Christian's (the OP), I like your gear and check it regularly when I'm in Europe just think you could have contributed to this post better than dropping your product without any explanation.
Hi Christian, how much are you retailing individual units for so others know what to put away for xmas?
Yes I understand it was awkward. Sorry I did not want to hurt anyone. :-(

I leave this post and I wish you good day.
Hello Mr. Drotek
What´s wrong with u? I do not understand how to react so negatively to legitimate criticism. when I compare both products, I would not buy your product. Realy!
YOUR comment was stupid.
P.S. I use the big one (200A) in a Big Hexa (over 5kg) with 5S and 120A average. Christians Board works reliably. Better as the original from 3DR!!
