There are several components whose footprint has a 180° or even 90°
|
||||
rotational symmetry, but the component's electrical function is not symmetric.
|
||||
Therefore, if such a component is incorrectly rotated, it will appear to the
|
||||
casual observer to be properly placed, but it will not work.
|
||||
<P>
|
||||
These components are:
|
||||
<UL>
|
||||
<LI>the transceiver chip,
|
||||
<LI>the microcontroller (<B>atusb</B> only),
|
||||
<LI>the balun, and
|
||||
<LI>the LED (<B>atusb</B> only)
|
||||
</UL>

<SUBSECTION title="atben components">

<B>atben</B> only has the transceiver and the balun. The markings on

both face towards the crystal and the antenna:

The corner next to pin 1 of the transceiver is marked with small dot.
|
||||
The picture above also shows the orientation of the text printed on
|
||||
the package. The balun is marked with a square between pins 1 and 6.

In <B>atusb</B>, the marking on the transceiver is on the corner between
|
||||
the crystal and the antenna. The marking on the balun faces towards the
|

antenna. The microcontroller's "top" side faces towards the USB connector.

|

It is difficult to determine the LED's orientation by visual inspection.
|
||||
An efficient approach is to touch the LED's terminals with the probes
|
||||
of a multimeter set to measure resistance. The small current used for
|
||||
the measurement will light the LED.
