LT-280 24-channel SPI Driver Manual
LED RGB driver is a kind of multiple-channel controller which receives standard
SPI(TTL) signal, extensively used to control LED lamp which has no IC in it.
It can achieve effect such as RGB scanning, color-chasing, animation and so on.
The controlling channels and the output power can be repeated unlimitedly.
Note
：
Apart from receiving SPI (TTL) signal, LT-280 can also work with our
LT-8020 DMX decoder to receive international standard DMX signal and
control each pixel separately.
Suitable for LED decorative products such as LED sign modules, LED strips,
LED tubes, LED projectors, LED flood lights and so on.
