Dual BEC H Type
The HUBOSD8 has been engineered to provide the highest possible performance and reliability in a 4 layers PCB.
It is a multifunctional HUB with PDB, BEC 5V/2A &12V/500mA, Current sensor 140A, STOSD8.
The BEC 12V is linear regulator, no LC Filter needed.
Built-in STOSD8 can support Plug & Play, no complicated settings needed.
It is specially made for the mini FPV Quad.

Current Sensor
140A
If current >140A. STOSD display 140A

STOSD-8
1) Running indicator
Blue LED blinks: STOSD is initializing
Blue LED light: STOSD is working.
2) Autodetect PAL/NTSC
Auto sense PAL / NTSC cam at OSD startup. Default is NTSC without Cam signal
3) Dynamic on screen info
Current < 2A & keep 5 seconds
Current > 2A
4) Min.Volt & Max.Amp recorder
5) Automatic flight timer
Current > 2A, Time in.
Current < 2A,Time out.
6) Auto battery cells detection
If the Input voltage is in the range of following, The HUBOSD will detect the cell
numbers automatically.
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
