The newest update to the SP501E controller just hit the shelves. Like the SP501E, it has an ESP8285 chip with 2MB flash. Unlike the SP501E, it has dual outputs (on a single pin), includes 3 case buttons, built in mic, and a 38 key IR remote. It also sells for slightly less at $12 on Amazon and under…

There was an issue with preset scrolling with bounds. Blaz fixed it some time after b3, I’m not sure if the fix is in b4 or not. Once we have that fix, you can get your music buttons (both IR and on the enclosure) to cycle through just your music presets. If you look on the “Tips” section of the JS…

Does anyone know the reason for the high LED memory usage on my SP511E? [Screen Shot 2022-01-26 at 11.56.33 AM] I’ve entered 266 LEDs, but I need 268. Running v0.13.0-b6 SP511E_2M.bin from WLED-wemos-shield/resources/Firmware/WLED_wemos_shield/v0.13.0-b6 at master · srg74/WLED-wemos-shield · Git…

My nodes running SR 0.13.0_b3 show 5000 B. Not sure why the 20% reduction.

You are using GPIO3 which uses a lot more memory than the others. See here. Multi-strip Support - WLED Project

Thanks for the information @Artacus and @tonyno GPIO3 is the third pin that allows hardware driving on ESP8266. However, it uses 5 times as much memory per LED as GPIO 1 and 2, so use it only for low LED counts (recommended <50) Specifically for the SP511E, does that mean additional modifications…

Hi guys. The max ampere is stated with 6A. Is this correct? Can I power about 250 ws2812b LEDs through this thing? Should I stay with a max of 6A?

6A is pretty optimistic given the barrel connector they use for power, they’re normally only rated to 3A. Rough guesstimate on 250 LED’s @ 0.3W/LED => 75W worst case maximum. If they’re 5V strips, you’re looking at 15A maximum. Not a good idea to try and use the little wires (20AWG at best) comin…

@Artacus your link to the SP511e bin file is broken on your github. The sound reactive bin file is still there. Any particular reason why? Perhaps you could load some instructions on how we can tweak and generate our own bin file (supplementing the WLED documentation with the bits to made buttons w…

Serg deleted the beta builds after 0.13 was released. You can grab the latest here. WLED-wemos-shield/resources/Firmware/WLED_wemos_shield/v0.13.2-a0 at master · srg74/WLED-wemos-shield · GitHub And the very first post in this thread has the platform.ini settings you’d need to build it yourself.

Divsys wrote up a great guide for modifying the SP511E. Looks like gpio 1 is your best bet because 2 is used for the power button. SP511E Upgrade project
