 # HyperSerialWLED
-Fork of the WLED project where the Adalight USB serial protocol @115200 speed is replaced with the AWA protocol with data integrity check at @2000000 speed for use with [HyperHDR](https://github.com/awawa-dev/HyperHDR).<br/><br/>
-Now it's possible to use HyperSerialWLED with any LED strip/pinout supported by the WLED.<br/>

+**In the releases you can also find special version working at only 921600 in case if your serial port chip doesn't support 2Mb speed.  
+The project will not follow WLED releases anymore unless there is a serious reason. It's design to help you setup your LED strip. Then you should migrate to HyperSerialEsp8266 or HyperSerialESP32 because choosing fast USB solution you don't need a Wifi. So in this case those projects offer you lower power usage, less electromagnetic interference and more available resources.**
