Smart pixels come in many variations, but the majority of them are driven with with 5Vdc CMOS logic levels. The output pixels maybe powered with 5V or 12V, but the input control levels are 5Vdc CMOS. The one exception to this rule would be the TLS3000’s series which require 3.3Vdc input logic. The list of 5Vdc logic inputs includes the following:
- WS2801, WS2811, WS2812
- TM1803, TM1804, TM1809, TM1829
This board supports driving pixels directly by converting the 3.3Vdc CMOS outputs from the FPGA to 5Vdc levels. Also, included on the board are source termination resistors (100 ohm recommended).
