LAMOST is a horizontal reflex Schmidt telescope with a large field of view and large aperture. The installation of 5,000 fiber positioning units on a 1.5 m diameter focal panel requires a miniaturized design. This paper uses TI's CC2530 microcontroller and Allegro's A3888 driver chip, combined with ZigBee wireless communication technology, to complete the design of the drive of the fiber positioning unit, and related to the progress of the test, the experimental results meet the design requirements.
