    223223 * Note that the above descriptions are board-specific. Please see the board [http://www.gateworks.com/usermanuals Hardware User Manual] 'System Temperature and Voltage Monitor' section for details. Note also that Vin (Board Input voltage) is evaluated at the board's primary power supply input and offset by an estimated diode drop and thus may differ from your actual power supply within a volt or so.
     224 * Note that older versions of the GSC hwmon driver in the Gateworks 3.14 kernel (Android / Yocto) and OpenWrt 14.08 / OpenWrt 16.02 report temperature as 'temp0' instead of 'temp1'.
    224225
    225226A Linux 'Hardware Monitor' ({{{hwmon}}}) driver is available in OpenWrt which provides simple standard access to the above temperature/voltage registers via sysfs.  The arguments have been given labels which define the source. The user can “cat” the label to determine the source. See the following examples listed below.
