Zest_LED_WS2812B

Overview

The Zest_LED_WS2812B is an electronics development board for 6TRON open source platform based on WS2812B neo-pixel RGB LED from Worldsemi.

The LEDs are driven by a single serial data signal and each pixel is addressed by the 24 first bits of the frame received.

The Zest_LED_WS2812B offers 6TRON users a 5x8 LED matrix to display various information or graphics on a matrix LED display.
