Multimedia Expansion Board II (MEB II) User's Guide
2.1.10
The MEB II includes a Microchip MCP9700T analog temperature sensor, as shown in
Figure
The MCP9700 Linear Active Thermistor™ IC is an analog temperature sensor that con-
verts temperature to an analog voltage. The MCP9700 provides a low-cost solution for
applications that require measurement of a relative change of temperature with ±1°C
accuracy at room temperature.

The MEB II includes a microSD card slot that interfaces to the PIC32 microcontroller
through an SD Interface, as shown in
FIGURE 2-11:
Note:
2.1.12
The MEB II includes two touch buttons that use the Microchip mTouch™ technology,
as shown in
two analog channels.

microSD Card Slot
microSD CARD SLOT
In an application, since Bluetooth and microSD share the same pins on the
board, only one can be used at any given time.
Touch Buttons
