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.
This is the all-new Omnibus F4 Pro, based on the design of the popular Omnibus F3 Pro. However, the main advantage of this board is that it uses the more powerful STM F4 processor for even faster loop times. It has all the other things you love from the Omnibus F3 pro including an OSD module, SD card reader, low noise IC268G IMU connected via SPI, a current and voltage sensor, etc.The V2 pro version now includes a built-in BEC, so you can power this board directly from your flight battery (up to 4s)
