ME-DIGITAL POTENTIOMETER BOARD To extend the capabilities of their debug boards, many manufacturers offer additional peripheral device modules. Many of such modules that significantly simplify the development process are produced by mikroElectronika. ME is a digital potentiometer board based on the MCP41010 microchip. MCP41010 is a single-channel 8-bit digital potentiometer with 256 control steps and a standard serial peripheral interface. Its impedance is 10 kOhm. The board is connected to the main board with a 10-pin connector. Depending on the microcontroller type at hand, turn on the relevant switches. For instance, for an EasyAVR5A board, the third and the sixth switches need to be turned on. The board is connected to the device under test with a labeled terminal block. Other features of the digital potentiometer board are the availability of a register for saving rated values and an off command to decrease power consumption. Digital potentiometers are widely used in audio equipment (volume and tone control devices), in servodrive controllers, battery chargers and many other devices.
