# dh360d: reconstructing the Darkflash cooler LCD protocol

> dh360d reconstructs the Darkflash DH360D cooler LCD's serial protocol from traffic captured between the hardware and its Windows Electron app. Its Python Linux driver sends CPU temperature, pump speed, CPU use and RAM use through a CH340 USB-to-UART link. The protocol notes specify the 115200-baud framing, handshake, status fields and device acknowledgments.
