Product description
Flora NeoPixel v2 – chainable RGB LED for wearable projects
This second version of Flora NeoPixels is specifically designed for wearable electronics and includes a constant current driver integrated into the LED package. The pixels are chainable – only one pin is needed to control multiple LEDs. They are easy to sew onto fabric, and the layout prevents crossed threads.
Version 2 communicates at high speed (800 kHz) and is not backward-compatible with version 1, which used 400 kHz. Full 24-bit colour rendering is managed via integrated PWM control. Due to the high brightness, less current is needed for the same visual effect, and the constant current driver ensures stable performance even with minor battery voltage fluctuations.
Each pixel can draw up to 60 mA at full brightness (white). In theory, Flora can drive up to 500 pixels at 30 FPS, but after approximately 10 pixels – or at longer distances between pixels – the resistance of the conductive thread can affect power delivery. For more than 10 pixels, it is recommended to use copper wire or braid as a power bus.
