NeoPixel Jewel RGBW (Natural White) Not Working

Post by mtaylor5 »

Hello,

I ordered 2 NeoPixel Jewel's RGBW (Natural White) for a project along with a NeoPixel Strip and NeoPixel Ring. Both the strip and ring work fine with the code and wiring I am using. The problem is the NeoPixel Jewels. I tried the first one by soldering on headers and it didn't work. I double checked all of the connections and they were correct. I looked and the centre LED and it was very very faintly blue. I tried to re-solder the connections but it still didn't work. I tried the second one and the exact same thing happened. I double checked again and the Ring and Strip still worked the correct way.

(Blue LED much less bright than what it looks like in photo)
Any help appreciated,

Matt

Are the jewels connected directly to the processor - or daisy-chained to the end of the strips?
An overall photo showing all your connections would be helpful.

They are connected directly to the Microcontroller (an ESP8266) through a 3.3 to 5v logic level converter.
Here is exactly what I have done on the breadboard:

Try removing the resistor on the signal wire and connecting directly to the output of the 74AHCT125.
