Realacc HUBOSD ECO H Type w/STOSD8 Current Sensor 5V 12V Dual BEC PDB
The HUBOSD eco has been engineered to provide the highest possible performance and reliability in a 46*36mm & 4 layers PCB.
It is a multifunctional HUB with PDB, BEC 5V/2A &12V/500mA, Current sensor 140A, STOSD8. It is specially made for the mini FPV Quad.
The BEC 12V is linear regulator, no LC Filter needed. Built-in STOSD8 can support Plug & Play, no complicated settings needed.

If the battery is 3S LiPo, Output voltage=3S LiPo voltage – 1V
If current >140A. STOSD display 140A
Blue LED blinks: STOSD is initializing
Blue LED light: STOSD is working.
Auto sense PAL / NTSC cam at OSD startup. Default is NTSC without Cam signal
Dynamic on screen info
Current < 2A & keep 5 seconds Current > 2A
Min.Volt & Max.Amp recorder
Automatic flight timer
Current > 2A, Time in. Current < 2A,Time out..
Auto battery cells detection
If the Input voltage is in the range of following, The HUBOSD will detect the cell
11.1~13.05V: 3cells LiPo, 14.8~17.4V: 4cells LiPo, 18.5~21V: 5cells LiPo
If the input voltage is out of the range. The voltage value will blink on screen.
Pls check if the battery total voltage is below 3.7V*cells
Low vlotage alarm
