EDU450 Carrier Board
Introduction
The EDU-450 carrier board is a highly integrated component specifically designed to seamlessly integrate into the EDU450 drone frame. Its primary aim is to effectively minimize the common issues related to wire and module entanglement often experienced during multi-rotor assembly. This carrier board offers a range of features, including built-in power distribution, redundant power supplies for the autopilot, fail-over power selection built-in as a backup, a dedicated payload power regulator, and various other functionalities.
This carrier board is primarily designed with geometric optimization for quadcopters, X8 configurations, and octocopters in mind, it offers connections for all functions of The Cube autopilot. Consequently, this board can be seamlessly integrated into any vehicle type that is compatible with The Cube autopilot system.
Features
Up to 8-cell Lithium battery (36V)
100A continuous current
Power and signal for ESCs
5V navigation light port
Built-in power distribution unit
Built-in Hall effect voltage and current sensor
Redundant power supplies for flight critical components
Built-in 5V/10A, 7V/1.5A BEC
Main power Failure indicator lights
Connectors for all functions of Cube
485 and SPI port
Power
The carrier board incorporates built-in voltage and current Hall sensor. Users can directly connect the main battery to the XT60 "MAIN PWR" on the board, eliminating the need for an external power brick.
The power distribution system is rated to distribute 100A in total to the ESCs when exposed to stagnant air at room temperature.
If the EDU450 Carrier Board will be installed inside an enclosure or used in challenging conditions, like high temperatures, it might be essential to reduce the current capacity rating. For users who anticipate running their vehicle at consistently high currents, it is advisable to conduct a ground test by using a temperature gun before flight.
Specification
Size：170 mm x 145 mm
Weight：185g（with carbon fiber plate）
Port Interface
RS485 & SPI
The carrier board introduces enhancements such as anti-interference capabilities, high-sensitivity RS485, and a full-duplex, high-speed, synchronous serial communication SPI interface. This interface can be used to connect with Profi-LED or a range of industrial equipment, thereby offering increased communication support for extended equipment and a broader spectrum of applications.
Customized port for HerePro
The carrier board features a dedicated HerePro special interface designed to streamline data , debugging, and power supply functions into a single connection point, enhancing overall integration and reducing the need for excess wiring.
ADS_B External Antenna
The integrated ADS-B system is employed for receiving air traffic information, and it includes a standard SMA interface for user convenience. Users have the option to connect an external antenna to expand the data receiving range.

Note: Please connect receiver to PPM（as picture showed），other 2 "SBUS" s are Sbus out
5V BEC
The board can supply 5V to the Main and AUX rail by bridging the following pad with solder.
ProfiLed
The carrier board has 4 built-in ProfiLed interfaces for the connection and control of navigation lights.
ESC Port
ESCs used Amass-MR30 connector to power the motor and transmit PWM signal.
The 8 ESC port in total is available for multi-rotor UAVs with four and coaxial eight rotors.
