SPI controller


  1. If the SPI LED strip is a single-wire control method, the DATA and CLK signal line outputs of the controller are same, and one controller can connect 4 LED strips.
  2. When the load exceeds 8A, the light strip needs to be powered by other power supplies.
  3. Only DATA/CLK and GND cables are connected between the controller and the light strip.

Match R9 remote control

Match: short press on the match key, immediately press on/off key of the remote. The LED indicator fast flash a few times means match is successful.

Delete: press and hold match key for 10s to delete all match. The LED indicator fast flash a few times means all matched remotes were deleted.

Set the length, chip type and RGB order of the SPI LED strip using R9 remote control
