ARDUINO M336 HP07 Digipot Interface Module Electronic Components Electronic Hobby Kit

Resistance can be digitally set* to the required value without any manual labor unlike ordinary potentiometers. For manual setting, the on-board DIP switch can be used to set the resistance to the required value without any measurement (to set the resistance in an ordinary potentiometer, the resistance has to measured and accordingly the potentiometer knob is rotated)The module is 5V/3.3V compatible making it suitable for interfacing with all microcontrollers and development boards like the 5V Arduino and 3.3V MSP430.The interface can be set to either parallel or serial by asserting the P/S’ pin on the module. The serial or parallel modes can be changed during run-time without powering down.Parallel input can be supplied from a digital circuit through the header pins or using the on-board DIP switches depending on a jumper position.Compatible with a range of industry standard digital potentiometers.
