OpenServo is an open community-based project with the goal of creating a high quality digital servo for robotics.

Some of the many features of the OpenServo include:
  • High performance AVR 8-bit microcontroller
  • Compact H-Bridge with high performance MOSFETs
  • Precision control over servo position and speed
  • I2C/TWI based interface for control and feedback
  • Feedback of position, speed, voltage and power
  • Advanced curve based motion profile support
  • EEPROM storage of servo configuration information
  • Software written in C using free development tools
  • I2C/TWI bootloader and GUI programmer
