NEXUS Flybarless (FBL) unit is designed based on Rotorflight 2.0 with excellent performance and compatibility for RC helicopter fans. With an advanced MCU STM32F722 and a six-axis motion tracking device TDK ICM-42688-P, NEXUS ensures precise control and stable flight. Built-in 128 MB memory enables comprehensive flight records for fine-tuning.
Properties:
- The NEXUS helicopter controller is designed specifically for Rotorflight 2.0.
- Equipped with advanced processor STM32F722 MCU and 6-axis MEMS device TDK which combines 3-axis gyroscope and 3-axis accelerometer.
- Built-in Black Box: A large memory of 128 MB ensures the ability to record all flights for fine-tuning and editing.
- Connector system with lock, compatible with Plug'n'Play receivers without the need for soldering RP3-H ExpressLRS (RP3-H not included).
- Functional UART ports for future expansion.
- The NEXUS control unit is compact and durable. The CNC aluminum case not only protects the internal components, but also serves as a heatsink to keep the temperature of the electronics low.
- NEXUS measures 41mm x 25mm x 13mm, making it an ideal choice for a variety of helicopter sizes, including 250/450/500/550/600/700 models.
- The controller supports a wide range of rear motors and tail servo ESCs (760μs / 1520μs).
- Supports various receivers, including CRSF, ELRS, GHOST, S.BUS, SUMD, IBUS, XBUS, EXBUS, PPM, MSP, DSM2, DSMX, F PORT.
- The device has several independent power supplies that minimize noise when they reach 1.8V. Contains 1.8V for gyroscope, 3.3V for MCU and 5.0V for external interface.
- A light and flexible USB-C extension cable is included in the package and helps in situations where the USB-C port is difficult to access. It's designed with minimal weight because every gram counts, and features flexible silicone wires that limit the transmission of vibrations to the control unit.
- Standard Rotorflight Rescue feature.
