Description

The SSI 2130 offers unprecedented performance and features, but its ultra-compact QFN package can present prototyping challenges. The EVB2130 eases evaluation by providing a PCB
that allows comprehensive exploration of capabilities.

The EVB 2130-B blank board has the SSI2130 pre-soldered, all remaining components are through-hole for easy construction and experimentation. The through hole parts are not included.

A on-board +5V regulator and 2.5V reference simplify external power connections, and pots are provided for mixer control, PWM, and VCO setup. Switches ease selection of saw ramp
direction plus Through-Zero and Pulse Modulation. The schematic, bill of materials, and a user guide are available here – https://www.soundsemiconductor.com/downloads/evb2130.pdf
