External Speaker
A miniature 8 ohm speaker can be connected between JS5 pin A30 (Speaker -) and JS5 pin A29
(S). A speaker is provided on the CBR-8001 breakout cable.
Push-Button Reset
Connector JS5 includes an input for a push-button reset switch. Shorting JS5 pin B19
(Pushbutton Reset) to ground causes the EPM-32 to reboot.
This connector uses IEC 61000-4-2-rated TVS components to help protect against ESD damage.
A reset button is provided on the CBR-8001 breakout cable.
IDE LED
Connector JS5 includes an output signal for attaching an IDE Activity LED. Connect the cathode
of the LED to JS5 pin A32, and connect the anode to +5V. An on-board resistor limits the
current to 15 mA when the circuit is turned on. An IDE LED is provided on the CBR-8001
breakout cable.
