Board not appearing as a COM port
Install the CP210x driver: CP210x_Universal_Windows_Driver.zip. Try a different USB cable (some cables are charge-only and carry no data), and try a different USB port on your computer.
Connection drops unexpectedly
You should disable the power saving feature of the USB port. In Device Manager, find the CP210x device under Ports (COM & LPT), open its Properties → Power Management, and uncheck "Allow the computer to turn off this device to save power".
Cannot connect over WiFi
- Verify the IP address; check your router's DHCP table, or reconnect via USB to see the current address shown in Initial motor configuration and settings.
- Make sure the board and the PC are on the same network.
- Check that no firewall is blocking UDP port 10000.
- Confirm that Station mode is enabled and the board has successfully joined your network.
Shutter board not connecting
- The rotator↔shutter link is a private, internal Wi-Fi connection that pairs automatically—no network settings to check here. If it is not coming up, power-cycle both boards.
- Make sure both boards are powered and within range of each other.
- Initial motor configuration and settings waits up to 30 seconds for the shutter, be patient after connecting the rotator.
