$25.00

Alex Mos brushless Gimbal controller in the EU Latest version.

This is the latest version that will support all the new features of the next upcoming firmwares.

3rd Axis can be directly plugged / soldered.

In addition to the new features of Base Flight different modifications where done to allow for safer operation.

The performance of this board is strong enough for virtually all cases, even large engines like the 8017 does not really draw much power, about 1A at 4S, so even here a parallel operation of two motors is possible.

IMPORTANT NOTE: you will loose all previous setting after upgrading to this version.
!!PLEASE, SAVE SETTINGS TO FILE BEFORE UPGRADING!!

• Bug fixed: multiple YAW turns caused variable overflow and instability
• Bug fixed: if the system starts in the YAW lock mode, the camera can accidentally  rotate to fixed angle.
• Bug fixed: in Follow PITCH mode, if camera is pitched by 30-50 degree, ROLL looses horizon level if panning by YAW.
• Follow PITCH mode extended by the new setting to configure the ROLL axis lock-to-follow transition.
• If Flight Controller (EXT_FC) is connected and calibrated, the system becomes more stable in the bigger range of inclination angles (even pitched +-80 degrees)
• Battery monitoring and buzzer:
  • Voltage drop compensation (PID becomes stable during whole battery lifecycle)
  • Low-Voltage alarms and motor cut-off
    (This feature will be supported on some newest boards or old ones with the hardware mod. See user manual for details.)
• RC mapping improved: Any of PWM, Sum-PPM, or Analog modes may be set for any of RC inputs separately.
  • it lets to use YAW-encoder or joystick together with RC control or External Flight Controller
  • it may be required to re-configure RC inputs after firmware upgrade
• RC mix option: you can mix 2 inputs together before applying to any of ROLL, PITCH or YAW axis. It lets to control camera  from 2 sources (joystick and remote for example)
• Serial API extended by the ‘C’ command (camera control). Example written in C++ for Arduino is provided in doc.
• New option to limit angular accelerations in case of hard RC or Serial control (useful to prevents jerks or skipped steps, smoother camera control, less impact on multirotor’s frame)
• PID settings: I-term internally multiplied by P-term to increase I response when P is high.
• “Compensate acceleration” algorythm removed to free up program space for more important features
• (GUI) New Full-screen mode available to better fit GUI in small displays
• (GUI) Bug fixed: firmware upgrade fails if working path contains spaces.
• (GUI) New button to switch motors ON/OFF
• (GUI) Italian and Czech translation (thanks to Iacopo Boccalari, Lubos Chatval)
• (GUI) 2 new high-contrast themes for outdoor usage
• (GUI) New red marker: shows RC controlled angle that gimbal should maintain

What’s new

Firmware: SimpleBGC_2_2b2.enc.hex

GUI: SimpleBGC_GUI_2_2b2.zip
User manual: SimpleBGC_manual_2_2_eng.pdf

• New camera control mode: “Follow Pitch” mode (video tutorial)
• New tab in the GUI to configure this mode
• Smooth switching between modes on-the-fly
• User manual for v.2.2

Version 2.1 Released

What’s new

• New option: skip gyro calibration at start-up. With this option checked, board starts working immediately after power ON.

• New menu command and GUI button for manual gyro calibration
• RC Map, RC Source moved to profiles. It allows to change RC control setting by switching profiles.
  (warning: after firmware upgrade, old RC Map setting will be lost)
• RC YAW axis control may be  inverted now by specifying Min.angle > Max.angle, like for other axis (but this setting not used for limiting, just for inverting).
• I2C errors monitoring: LED will blink when I2C error detected
• New option: gyro high sensitivity. It doubles sensitivity of the gyro, that  equals to multiplying gains in the PID controller by 2.
  It may be useful for big DSLR cameras.
• Translation to Chinese (thanks to Max) and Polish (thanks to Tomasz Ciemnoczulowski) language versions done.
• The “Firmware Upgrade” tab in the GUI is working now and allows to upload a new firmware.
