In the present work, a modular and low-cost FPGA-based phased array system was developed that uses transducers emitting at 40 kHz for the acoustic levitation of small objects (≤ 4 mm). The system consists of a driver board, transducer arrays with various layouts, and software developed in MATLAB®. The software can be used to simulate the acoustic field, calculate acoustic traps, and control the driver board via a provided USB-SPI interface. The driver board controls up to 100 channels simultaneously with square-wave signals up to 20 Vpp with π/1024 phase resolution and 10 bit amplitude resolution. Several phased arrays can be linked via a provided I2C interface to increase the number of available channels. The functionality of the system is demonstrated by the levitation of small objects using a flat 40 kHz transducer array.
