5. LED Drive
The indicator LED should be bicolor, because red, green and amber (red+green) are used to indicate status.
The LED drive pins will auto-detect common anode or common cathode parts. The detection is done by
looking to see which way up the LED_RED pin is idling at boot; to ensure this works correctly, please place a
100k resistor in parallel with the red LED.
The current drive on these pins is 20mA maximum.
Please refer to paragraph 14 for the recommended LEDs.

6. Phototransistor
The phototransistor is used to receive BlinkUp configuration data. The bias resistor connected between
OPTO_IN and GND may need to be adjusted to ensure adequate sensitivity and response time - in general
you need at least 500mV swing on the OPTO_IN pin between black and white states, with the worst
(dimmest) BlinkUp sender you can find.
End-user BlinkUp send data at between 30 and 60 bits per second, depending on the user’s device. For
factory configuration, data is typically sent at 142 bits per second using red LED(s) in a test fixture. If your
application does not require optical configuration, config can be sent electrically at 120 bits per second from
another micro using the OPTO_IN pin. Please contact us for more details.
Please refer to paragraph 14 for the recommended phototransistors.
