Eterna Mote Modules

The Eterna mote modules are shown in Figure 11 and Figure 12. Pins are described in Table 2, where they are grouped by

function. In some cases, a pin may have multiple possible functions.

Note: All unused input pins not configured with a pull resistor (see Pull column in pin out table) must be driven to an

inactive state to avoid excess leakage and undesired operation. Leakage due to floating inputs can be substantially greater

than Eterna’s average power consumption.
