USB 2.0 cable - this cable is required to upload the firmware from a PC or Raspberry Pi with the Home Assistant control system installed on them into the controller based on the ESP32 processor. To work properly with a Windows PC, you need to download and install the driver of the built-in USB-UART adapter (https://www.silabs.com/developers/usb-to-uart-bridge-vcp-drivers)
