Universal 2-axis 2-axle Brushless Gimbal Controller Open Source V049 Martinez

Gimbal controller supported 2-Axis brushless motors and is adjustable, so it can be balanced for camera perfectly.
The original version Brushless Gimbal Controller by Ludwig Färber (Hardware and Software) , Alexander Rehfeldt (Software) and Christian Winkler (Software).
This is an Open Source Project. We add a MOSFET for reverse polarity protection and a status blue LED for status indication.
When you running original firmware (e.g. 049) the LED will show you the startup status.

Cable Description: 
German version of the firmware: 
Input: A1 is PITCH (pitch) control, A2 is ROLL (roll) control 
Back screen "PITCH" position represents the pitch axis output, "ROLL" position shows a cross-roller output 
IMU board mounting direction: underside (flat) up, x /-x-axis pointing to the front and rear head direction, y /-y axis pointing to the side of the head 
Russian version of the firmware: 
Input: A0 is PITCH (pitch) control, A1 is ROLL (roll) control
