Sparkfun EiBotBoard

The EiBotBoard (EBB) is a compact, versatile two-channel stepper motor driver board, measuring 5.6 cm x 5.6 cm, equipped with a USB microcontroller. Designed initially for the Egg-Bot project, it offers enhanced functionality by supporting various commands, including stepper motor and RC servo output commands. The board can control up to seven RC servo motors simultaneously, with a built-in 5V power regulator to support them. For additional power needs, an extra input circuit is available on the back of the board. The EBB connects effortlessly to a PC via USB, appearing as a serial port, and allows easy command input through a terminal emulator or custom applications.

Perfect for robotics enthusiasts and hobbyists, the EiBotBoard simplifies the process of controlling stepper motors directly from a computer. Whether you're building a custom CNC machine, a 3D printer, or a robotic arm, this board provides the necessary tools to bring your projects to life. Its compatibility with Windows, Mac, and Linux systems ensures a wide range of applications, making it a flexible choice for various technical endeavors.

The EiBotBoard's unique ability to handle multiple RC servos alongside stepper motors sets it apart from conventional driver boards. This feature offers significant advantages in projects requiring synchronized motor movements, such as animatronics or complex motion systems. The microstepping chopper stepper motor drivers ensure smooth and precise motor control, enhancing the overall performance of your creations.

For those concerned with hardware safety, the board includes a thoughtful design consideration: the use of plastic washers when employing metal mounting hardware to prevent shorts. This attention to detail underscores the board's reliability and user-friendliness, making it a trusted component for both beginner and advanced users.
