Seems some else has been down this rabbit hole as well:
Not the worst choice you could make given the PWM drivers builtin - if you need that.
The potential downsides I see:
- May be limited to the number of LEDs you could drive as you’ll be using up RAM pretty fast because of the GPIOs used, you hit a limit around 300+ LEDs for a single controller.
- No OTA updates of the firmware with 1M flash devices.
- Probably don’t want to try and pass 5A of current through those board traces, though that may not be an issue if you’re doing small(ish) displays.
Much will depend on the actual displays you try and drive.
Personally, I’d add PWM boards externally where required and go for something like the SP511E’s or graduate to the ESP32 based boards out there which will be much more capable and open up the full power of WLED.
YMMV of course if the majority of your displays are analog this might be a reasonable choice.
Follow WLED down the rabbit-hole and a world of possibilities opens up
