I run out of variable memory very quickly.

I run out of variable memory very quickly. I was planning on using nanos to drive my led string logic in production. But with the need for more sram, I need more. The obvious choice is the mega, but is there a smaller form factor with 4k ish sram?

The LC would do it, but I’d say consider spending $9 more and get the Teensy 3.2 instead of the Teensy LC. Here’s how the two compare:

And here’s how the size compares to an Arduino UNO.

@Gregg_Novosad There is also the NodeMCU

Thanks. Quick question.

I will provide 5v power to the three leds separately .

But will the Teensylc handle 3 led strings’ signal pin out voltage correctly? Is this s 3.3v system or 5v system for signal voltage? Or does signal pin voltage not matter with ws2812?

WS2812 can handle both 3.3 or 5V logic. Although some will say otherwise…Personally, I use a booster pixel on all projects that have 3.3V logic.

thanks. I will give the teensy a go.

Also note the Teensy LC specifically has a pin with a 3v3 -> 5v level converter for driving WS2812s (pin17) https://www.pjrc.com/teensy/teensyLC.html

Hw about Arduino Due? 96 KB SRAM

ESP8266 is also an option… I have some but not yet implemented anything on one yet… bonus, integrated WIFI.

@Justin_Eastman YEP the ESP8266 is awesome for driving both the WS2812b and the APA102

ordered 3 teensy. thanks
