Recently we've received a lot of feedback from users that alpha's power-on function is very much needed in their project, so we decide to release a Beta version first.
Since this Beta version is not perfect at present, if you have any questions, please reply to the post.

PLEASE NOTE:
Although in our tests, there is no failure to boot after reflashing the BIOS, please back up your files in advance, and do not remove the power supply during the reflashing process, so as to avoid serious consequences.
