Product size: L60*W35*H25 mm
Can change TTL (SPI) signal to RS485 signal, or change RS485 signal to TTL (SPI) signal.
Why need it: the TTL (SPI) controller signal wires to SPI LED strip usually is very short, because TTL (SPI) signal transforming distance is very short from the SPI controller, if you want to have multiple rolls of SPI led strips to be controlled in sync by the same SPI controller, from long distance away in different areas, you need change the TTL (SPI) signal to RS-485 signal which can transform very long distance like 200m. So you can have multiple SPI LED strips in different places (200m range) to run the SYNC effects from the same controller.
So this TTL-485 mutual converter is perfect for big project if you want all the SPI LED strips run in SYNC far away from each other in different areas.
