This is a WS2812 or WS2812B RGB LED controller based on the ESP-01 /ESP-01S. With this board, your will easy to make your colorful display project Feature：1. Main chip：ESP-01/ESP-01S（This board Not include the ESP-01/ESP-01S）2. Interface：3Pin PH2.0 for WS28123. Working voltage：DC 3.7V-5V (Support 3.7V Lipo battery)4. Usage：a. Power supply：3.7V Lipo battery connect to the VCC GND (2.54mm male header)b. Upload the code to ESP-01S(ESP-01)c. Plug the ESP-01S(ESP-01) to the moduleESP-01 module Features: 1. 802.11 b/g/n 2. Built-in Tensilica L106 ultra-low power 32-bit micro-MCU, main frequency support 80MHz and 160MHz, support RT0S 3. Built-in 10bit high precision ADC 4. Built-in TCP/IP protocol stack 5. Built-in TR switch, balun, LNA, power amplifier and matching network 6. Built-in PLL, voltage regulator and power management components with +20dBm output power in 802.11b mode7. Aggregation of A-MPDU and A-MSDU and protection interval of 0.4s 8. WiFi@2.4GHz, supports the NPA/WPA2 security mode 9. Support AT remote upgrade and cloud OTA upgrade 10. Support STA/AP/STA+AP working mode 11. Smart Config support (including Android and iOS devices) HSPl, UART, I2C, |2S, IR Remote Control, PWM, GPIo 12. The deep sleep holding current is 10uA, and the turn-off current is less than 5uA13. Wake up, connect and deliver packets within 2ms, standby power consumption less than 1.0mW(DTIM3) 14. Operating temperature range: -40C-125C 15. The firmware version is 1.0.1, the default baud rate is 115200, (AT+C1 OBAUD= modifiable baud rate), because the previous version of the module is 512k bytes, the storage space is not enough, so you can not upgrade this 1.0.1 version, but the cloud service also supports!Package included:1 sets WS2812 Module + ESP8266 ESP-01 Module + 16 bits LED light ring
