Just bought myself a PDB that has integrated OSD with current sensor – the HUBOSD PDB by Realacc.
Why I bought it
I am going to test some batteries, and needed a setup that can show me the current draw.
I have seen some mixed reviews about this board: some say it just works and easy to use, while some say they “burned out 3 in a month”. Anyway I was tempted to get it because it has all the features that I was looking for:
- integrated OSD, that isn’t minimOSD so I don’t have to mess with firmware hopefully (it uses STOSD)
- integrated current sensor that is rated up to 140A, so I can see mah used
- you can direct solder XT60 connector on the board
Spec
- 3S-5S, supports 8V – 21V
- Current rating: constant 120A, burst 140A
- Regulated 5V and 12V outputs
- Current Sensor 140A
- Built-in STOSD8
- Serial port (RX, TX, G) for firmware update
- Dedicated pads for VTX/Camera
- Dimensions: 51x36x4mm
- Weight: 9g
- Mounting holes – 30.5mm
Some photos
In the package, it comes with some hardware, XT60 connector, a 330uF capacitor and the PDB. The capacitor is used to reduce voltage spikes and noise, it should be soldered at Lipo input or Vcc/GND.
I am going to give this a try on a build in the future, but I am wondering if anyone’s had any experience with it?
By the way I got it from here.
I have this PDB sitting on my table for few months now. I plan to put it in my ZMR x210, just to see current consumption. I heard lot of problems with this PDB, so for new builds I will use betaflightF3.
Just finished my first build which utilizes this PDB/OSD. So far so good. I’m a new pilot and havent pushed my quad that hard, but I haven’t had much interference in the fpv video or any major dropouts. I used a pigtail instead of soldering the XT60 directly to the board to help against possible breakage. I’ve only been able to fly 6 packs so far, so cant speak to its longevity.
