Wireless, WS2812B RGB Light Ring, ESP8266, ESP-01S

Wireless, WS2812B RGB Light Ring, ESP8266, ESP-01S

Condition:
* New surplus stock, in OEM packaging. As pictured.

Additional Notes:
* NOTE: Requires you to write "Sketch" of LED sequence and send to module. See Data Sheet for Useful Links
* WE CANNOT PROVIDE PROGRAMMING
* Wireless Control module for WS2812 programmable RGB LED based on ESP-01S WiFi master. With it, you can control the light ring using an Arduino.
* NOTE; this unit requires you to develop software and setup Arduino using IDE programming support.

WIRELESS ESP-01S MODULE/CARRIER
* Control pin: GPIO2
* Interface: 3-pin PH2.0 connector
* Working voltage: DC 3.7V-5V (Note: the positive supply Vcc of the board is connected to the "Vcc" pin of the WS2812 3-pin connector. So use DC 3.7V-5V power supply source.

LED RING
* Outside Diameter: 4.5cm
* Inside Diameter 3.1 cm
* Chip: WS2812 (in LED)
* LED: 5050 package full color RGB
* Power: 5VDC
* Port: Digital Series
* 16 programmable RGB LEDs built in WS2812B driver. Cascading NRZ Single line interface. Each LED requires 8 bits/color (24bits) + a Reset (Latch) for a 25 bit data stream, so 16 would need a data stream of 400 bits.
* Sequence is from closest LED to Din to last LED in string,
* NOT like a Shift Register.
* Adjust brightness tricolor 256, 160,000-color TFT display, scanning frequency of not less than 400Hz / S
* Serial even level interface, via a signal line to complete the reception and decoding of data
* Refresh rate of 30 frames / sec, even low-level mode even series of not less than 512 points
* Send and receive data at speeds up to 800Kbps
* Highlight LED, light color high brightness consistency
* LEDs:
       • Red: ~625nm @ ~400mcd
       • Green: ~522nm @ ~700mcd
       • Blue: ~465nm @ 190mcd
