If you have a Golden Harvest v3, you can use the Seedling for USB charging and file transfer. But even if you do not own a Golden Harvest v3, you can use it to charge a single Li-ion cell via USB. Using the Seedling USB Module you can charge a single Li-ion cell with up to 1.4A either via wall adapter or USB port of your computer. A smart charging algorithm automatically detects the maximum charging current your power source can provide and limits it to this amount. The Seedling USB Module contains a safe charging circuit. However, do not let your saber charge unsupervised! Safety always first! Please make also sure to use a protected 18650 Li-ion battery. For safe charging, use a Panasonic NCR18650B or Keeppower 18650 Li-ion battery. The Seedling USB Module can get very hot when you are charging at 1.4A due to its tiny dimensions (smaller than 11 mm x 19 mm / 0.433″ x 0.748″). It has an overtemperature protection, but please make sure that the environment in which you want to use it can handle high temperatures. Additional important information can be found in the manual of the Seedling. Please make sure to read it.
All boards are fully tested before shipping. We cannot be held responsible for any damage that arises from a faulty install or use of the board.
