    so that you can embed speakers in multiple things and move the driver around between them? that could be handy. you can’t drive it with a normal amp though.

    beaglebone has been done

  • Product SEN-10701 | about 9 months ago

    the answer is “it depends”. I’ve used a 5V arduino as a i2c slave with a 3.3v beaglebone without issue. it works because the beaglebone’s pullups are strong enough to to handle the small current needed for i2c. I don’t know if this is true of this sensor.

    the difficulty is that the i2c address is hard coded the same on the sensor itself. it’s been suggested that you could use the sleep pin to put them all to sleep except the one you want to read. you can only read one at a time over i2c anyway. drawback is that it requires a digital pin for each sensor, or maybe an i2c port multiplier.

    other option might be to use one of the software i2c libraries that bitbang the protocol instead of using the hardware i2c interface..

    the product card link no longer works.

    I did fine this suggesting a possible way to use SPI to drive the chain

    it’s for people that are afraid of soldering anything but through hole

    the example code linked is for a WS2801, this WS2812 has no CKI line.

    class ratings are minimums, not maximums.

    this looks clumsy to connect multiple together to make a seamless sign. The Parola design fixes that in one direction. Also the Parola’s library would probably work for this module as well
