Single-ended 25 mm flexible COB LED filament in red, powered at 3 V with both contacts at one end. LEDs are in parallel on a flexible PCB with silicone coating; use a resistor to limit current to 50 mA max.
Positive LED filament contact. Adafruit states to power with 3V and that the anode positive is the metal end with a little hole in it.
Negative return contact for the LED filament. Adafruit says if it does not light immediately, try connecting the other way around.
| Pin | Position | Type | Function | Voltage |
|---|---|---|---|---|
| Anode (+) | metal end contact with little hole | power | Positive LED filament contact. Adafruit states to power with 3V and that the anode positive is the metal end with a little hole in it. | 3V nominal, use current-limiting resistor per Adafruit product page |
| Cathode (-) | other single-ended contact | ground | Negative return contact for the LED filament. Adafruit says if it does not light immediately, try connecting the other way around. | return for 3V LED filament drive |
WS2812/SK6812 NeoPixel strips, rings and Jewels, APA102 DotStar pixels, and plain analog RGB strips — each matched to its protocol and host, not just its connector.
