Note: * is required

Please fill it out during the registration stage↓

* 1. Introduction to project functions

Bluetooth Speaker

*2. Project attributes

Original, first time

* 3. Open source agreement

non-commercial use

Note: Altruism means self-interest, please read the following content carefully.

1. Embrace open source and give projects unlimited value. It is recommended that more than 80% of the core functions of the project be open source;
2. If a certain part of the function is irreplaceable and the project cannot solve the corresponding problem after deletion, then the function implemented by this part is the core function of the project; for example, if an electronic load is designed and a host computer software is designed to monitor power changes, the electronic The load is the core function, and the host computer software is the auxiliary function; for example, an isolated 485 module is used in the electronic load to communicate with the host computer, then the communication function implemented by this 485 module is an auxiliary function;
3. Projects should choose an open source agreement that suits them . If the project references other open source projects, the source should be indicated and follow the original author's open source agreement. It is recommended that original projects use the GPL3.0 open source agreement;
4. Functions implemented by directly quoting the original circuits or original codes of open source projects cannot be used as the core functions of one's own projects, and functions directly implemented using common modules on the market cannot be used as core functions of one's own projects.
