This product has been replaced by the SEWRGB v2 pixel.
A set of 5 sewable RGB pixels for wearable projects.
At the heart of the SEWRGB v0.1 pixel is a WS2812 LED. The WS2812 is an interesting device which has a SMD5050 RGB LED combined with a built in WS2811 controller chip. This chip controls the current to each of the internal LEDs and using PWM can produce 24-bit colour.
SEWRGB pixels can be daisy-chained into strings that can all be individuality controlled by a single pin on the micro controller. Though because of the possible hight current (~60mA) used per pixel and the high resistance in conductive thread, the number of pixels in a string and the spacing between them should be limited.
The flicker visible in the video is caused by the high impedance of the conductive thread and high current used by the LEDs. The impedance has been reduced by increasing the capacity of the on board capacitors soldered onto each pixel. Along with using extra through hole bulk capacitors distributed/sewn along the string of pixels.
The board is 14mm in diameter with a thickness of 1.6mm, and are supplied pre-assembled. The five boards are supplied along with two 100uF Axial Capacitors.
