<h2>How to determine the operating frequency range of a MICA2 or MICA2DOT mote.</h2>
<p>1) Read the frequency label on the MOTE. </p>
<p>2) If the frequency label is missing, you can tell what type of device you
have by looking at capacitor <a href="mica2back.jpg">C13 (MICA2)</a> or
<a href="mica2dotback.jpg">C12 (MICA2DOT)</a>.</p>
<p> <b><i>if</i></b> C13/C12 <b>IS NOT</b> populated (capacitor
missing), <b><i>then</i></b> the device is built to operate in the 868/915 MHz
range.</p>
<p> <b><i>if</i></b> C13/C12 <b>IS</b> populated (capacitor present), <i><b>then</b> </i>the
device is built to operate in the 433 MHz range</p>
<p>As yet, there is no processor accessible setting (in EEPROM, FLASH or other)
that indicates the device's operating frequency band.</p>
