    2626
     27The buzzer is a Soberton GT-0930RP2 ([http://www.soberton.com/NewFiles/Product%20PDFs/GT-0930RP2.pdf datasheet]). The buzzer has one control pin, tied to an FPGA output through a simple transistor circuit. The buzzer will only operate when the FPGA drives a logic 1 and a shunt is mounted on J4 (see image below). The pitch and volume can be controlled by modulating the frequency and duty cycle of the FPGA output driving the buzzer.
