This seems like a very surprising and unusual hardware design, the 1.808V voltage is already unusual. Note that this may break systems that are trying to set a range of say 1.8-2.0V if they actually need to set 2V. --Ns+rXoClsiczKO+Q Content-Type: application/pgp-signature; name="signature.asc" -----BEGIN PGP SIGNATURE----- iQEzBAABCgAdFiEEreZoqmdXGLWf4p/qJNaLcl1Uh9AFAmXM05EACgkQJNaLcl1U h9ByNwf9GVyH+zISFE14EUpDs4CKOlrfNB5r1iTl39OoJqiAJyn/K/Ag6Pou5RBg 3CfjummZrnzSeX6ZSQU7JWfPMpUOBF1ipvHdIGkG9kUyZuWIJYu85WG8KiCPS5pj AfJI+pTboFJ7Biqg/3rcpPyf88w8SSMhNZyM7F5/0FGzSgu9wf3RrKgdDwyUBZyt SHu1mfmH71mmZn1zx74hs/4KwkE/g+7dgbJDmFKCSMcMTBjQ6hYP4E5Y+YOe3vyI i4ITXjEsI/AEj3MD6Jh/Kwjnf2ou7qFiSaGF11XgCsv32lWfpOlAU5Mia1R72grr JVDLSXKI5SC7Z9/PM+VcGI5Nma43Ow== =hoBz -----END PGP SIGNATURE----- --Ns+rXoClsiczKO+Q--
