In order to work with more small gimbal, we design a mini controller and have the stock now.

The main board size is: 46.6x30mm

And size of Sensor is same as before

For the updated firmware to download link as below:

Here is changelog compared to 2.2 version:

v.2.3b5
- 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.
- 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: voltage divider 33k/10k connected to pin 19 and active buzzer connected to pin 32. See user manual for details (coming soon)
- 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.
- Serial API extended by the 'C' command (camera control). Example written in C++ for Arduino is provided in doc.
- (GUI) New Full-screen mode available to better fit GUI in small displays
- (GUI) Bug fixed: firmware upgrade fails if working path contains spaces
