** You might have to use Com Port 255 for the USB connection on computer. Otherwise there could be a connection issue with the BLHELISUITE.
Data Cable Note
Note: M2 Nylon Spacers are used on these boards. So you may need to get some M2 size spacers and screws.
** Warning: The default firmware shipped with the board has been tested and configured by the factory in working condition (factory flashed the board with tested firmware manually via USB). You will be responsible for damage (or any part of function not working) if you flash your own firmware. So you are recommended to use the default firmware which shipped with the board. Thank you for your understanding.
** Warning: You must be very be careful when you do soldering on this ESC because it is small. All IC components on this board are tiny so the soldering iron/gun might damage the ICs if it is overheat. So you must have good soldering skill (fast & clean) to do this job properly.
