Omnibus F4 is a new family of All-In-One (AIO) STM32F4 based flight controllers with integrated OSD (On-Screen-Display) for FPV purposes. Basically, it is Airbot F4 / Flip32 F4 with added MAX7456 and some minor tweaks.

• OSD connected via SPI bus
• VCP port
• 3 UART ports, UART3 is shared with I2C
• Hardware inverter on UART1 allows to connect S.Bus receivers
• Dedicated PPM/S.Bus connector
• DSMX connecter
• PWM connector that allows to connect 4 PWM channels
• Integrated voltage stabilizer and voltage monitoring
• Analog current monitoring
• Analog RSSI monitoring
• Buzzer connector
• Integrated 16MB Blackbox flash memory

Notes:

• RAM pins are connected only to each other. For OSD only GND and Video IN and Video OUT lines have to be connected with camera and VTX
• Integrated voltage stabilizer tends to get hot when powered from 4S. Do not try to power camera or VTX from it
• Current and RSSI are NOT 5V tolerant. 3.3V max
• S.Bus and DSMX are shared with UART1
• To use UART1 and PPM, SBUS jumper has to be removed
