On the PU, close the jumper JP1. Connect one end of the USB-microUSB cable to the PU and the other to the PC. Turn on the PU power.
Since the drivers are copied to the system automatically when installing USB_Burning_Tool, they will either be installed automatically when the board is connected, or the wizard for installing new hardware (drivers) will start. In the latter case, simply agree with everything that the wizard offers.
If the drivers are successfully installed, a line with a new connected device (PU) will appear in the upper table in the main window of the USB_Burning_Tool program.

Click the Stop button and close the USB_Burning_Tool program.

Turn off the power supply of the PU. Disconnect the USB‐microUSB cable from the PU and from the PC. Remove the jumper JP1.
Everything is ready! You can assemble the miner, connect all the wires and start it up
