This Flight Control has Built-in OSD (On Screen Display)/ BEC (Battery Eliminator Circuit)
BEC (Battery Eliminator Circuit):
In battery-powered equipment, a battery eliminator circuit (BEC) is an electronic voltage regulator used to power a subsystem at a different voltage without the need for a supplemental battery. BECs are commonly used in radio-controlled models, which need separate voltages to power the motor and the R/C equipment.
Feature:
- Flight Control Built-in OSD / BEC
- Micro-SD Back-box
- Built-in Current Sensor
- F4 Processor (F405)
- On-Board Video Filter (only can supply 5V to VTX and Camera)
Package includes:
1 x F4 Pro V2 V3.5 v3s Flight Control Built-in OSD / BEC
