Alexmos 32bit 3 Axis Brushless Gimbal Controller – Basecamelectronics V 3.1

Description

The next generation Alexmos controller. High voltage support up to 6s (25v) specially for larger gimbals running 80 mm and larger brushless gimbal motors.

The controller can be used for building high-quality 3-axis camera stabilizing systems which can be mounted to UAV and for building handheld camera stabilizers.

This version of the controller is our new direction in the development of the stabilizing solutions. It will replace the previous 8-bit version of the SimpleBGC controller, keeping 100% back-compatibility, but adding the new fuctionality.

True 6S support (Upto 30V) and monitoring

 

 

 

Camera IMU Example

 

Basic functions of the controller

• 32-bit MCU — ARM Cortex M4. Effectively calculates the complex tasks for 3-axes stabilization.
• Allows camera control with the RC or analog joystick.
• Use several switchable profiles for different modes of operation
• Supports variety of RC protocols: PWM, Sum-PPM, spektrum and s-bus.
• Battery voltage monitoring, compensating voltage drop in the PID-regulator.
• Low battery alarm (output to 5V active buzzer).
• Increased number of inputs for controlling signals + 3 additional reserved input/output AUX1-AUX3.
• Can supply up to 1A current for external devices on the 5V power line.
• Dedicated UART-socket to connect optional Bluetooth module
• Reverse-polarity protection, overheat and over current protection
• USB interface for the PC connection, to configure, control and upgrade firmware.
• Graphical user interface to manage the settings. Windows / OS X / Linux versions.
• Control through the Serial-protocol using dedicated API.
• Improved attitude estimation algorithms
• Optional second IMU, that will increase the short-term precision of the stabilization 10x-30x times and  will make stable work in any frame position.

Note about brushless gimbals & Controllers

Brushless gimbals and controllers are very new to the market and is an emerging technology. You will need some patience and effort to get it to work as seen on youtube. THIS IS NOT A PLUG AND PLAY DEVICE!

You will need some understanding of Microsoft windows drivers, software settings and tuning the gimbal software to your liking and to suit your multirotor.

We will try our best to answer your questions and point you in the right direction but getting things to work the way it’s supposed to will be YOUR RESPONSIBILITY. Please understand this before you purchase any Brushless Gimbal Related Item.
