The Grover RGBLED ring (20WS2813 Mini) is a mini version of the WS2813 digital RGBLED ring. The RGBLED ring is a 3535-sized LED with a microcontroller embedded inside. Since the driver chip is located inside the LED, all WS2813 can be addressed. Each LED has a constant current driver, so even if the voltage changes, the color will be very consistent.
Record
The RGBLED ring (20-WS2813 Mini) is a mini version of the WS2813 digital RGBLED ring Grove-. The RGB LED ring is a 3535-sized LED, and a microcontroller is embedded inside the LED. Since the driver chip is located inside the LED, all WS2813 can be addressed. Each LED has a constant current driver, so even if the voltage changes, the color will be very consistent. Characteristics
The control circuit and RGB chip are integrated in the 3535 component to form an external control pixel
