Digital potentiometer shield
Arduino compatible digital potentiometer shield based on the Microchip MCP4261 digital potentiometer. This shield provides four 8-bit digital potentiometers with ranges of 5K, 10K, 50K or 100K.
An Arduino library which can be used to control the MCP4261 digital potentiometers can be found here iorodeo_arduino_libs. See the mcp4261/Examples directory for several example sketches.
The design files (KiCad) for the shield can be found here.
