OctoWS2811 + Teensy 3.6 + 24V LED strips

by Jeff Howard on Sat Nov 11, 2017 7:34 pm

Hey,
Hoping for some clarification here. I'm looking to use the OctoWS2811 board with a Teensy 3.6 to drive some 24V LED Strips. Specifically, 2 WS2811 strips that are 1, 800 LEDS each. The part that I'm unclear on, is power for the data signal. The OctoWS2811 will get me from the Teensy's 3.3V to 5V, but I could use some help figuring out if I need to do some level shifting to get that 5V up to 24V. If so, I've seen some posts in my initial research suggesting the use of a mosfet or some TIP42 transistors. Any help pointing me in the direction here would be much appreciated. Happy to provide further details if needed too.

Thanks,
Jeff

One more follow up here. I'm curious about compatibility between the OctoWS2811 and the Teensy 3.6. In reading the OctoWS2811 Adaptor page, it talks about the pins to use to be able to stack the 3.6 with the adaptor board. That led me to figure they were compatible. However, I looked at the page for the Teensy 3.6 again and noticed that the 3.5 is listed as 5V tolerant but the 3.6 is not. Can I provide 5V to the 5V pin on the adaptor board (in my case using a regulator to step down from my 24V power supplies), cut the VIN-VUSB pads and be alright using the 3.6? Or should I use a 3.5 instead?

Thanks!
Jeff Howard
