A 3V flexible LED filament chip, 260mm long, emits light in 360°, ideal for DIY projects. It's bendable, with distinct positive and negative electrodes.
positive electrode for the 3V flexible LED filament; DFRobot states the small round hole end is the positive electrode
negative electrode for the flexible LED filament; DFRobot states the non-porous end is the negative electrode
| Pin | Position | Type | Function | Voltage |
