The FrSky RXSR-FC (OMNIBUS F4 Fireworks) uses the ICM20608 over SPI to produce stable flight performance. Integrated with the RXSR receiver mounted on-board protection box, and the ICM20608 runs perfectly under 32k Gyro loop. Also onboard are a barometer and AB7456 OSD chip for the Betaflight integrated OSD.

The RXSR-FC (OMNIBUS F4 Fireworks) supports 3-6s Lipo direct input, built-in hall Current Sensor and Power Filter as well. The on Board PDB is tweaked by using 12-Layer PCB design. There is only 0.2-0.5 mohm internal resistance from input to each output pad.

Features:

• Tantalum Capacitors can be added to the board (not included)
• Solder pads added for VTXand Camera Control (next to Video pads)
• The orientation of IMU FPC optimized
• Gyro ribbon cable redesigned to fit without extending outside the board
• Added an 8v BEC and LC Filter for the camera and VTX power
• This board now has 5 UART ports

Specification:

• STM32 F405 MCU, Runs Betaflight firmware (supported from v3.2)
