Speaker Header JSPK
WARNING: The +5V pin is protected against a short circuit situation by a 0.1A PolySwitch. The JSPK
connector should be used exclusively for direct attachment of a dynamic speaker device. When
connecting to the input of a sound card, most likely a short-circuit situation will occur between the
+5V pin of the JSPK connector and the GND pin of the audio-card input, which could cause
permanent damage to the CC9-SAMBA and the audio board, despite the PolySwitch resettable fuse.
A workaround to this would be to place a 1k resistor across pin 1 and pin 2 of the JSPK connector,
and strapping a single wire cable from JSPK pin 2 to the audio input.
PLD Programming Header ISPCON
Note: The ISPCON is not stuffed. Its footprint is situated at the bottom side of the board.
