vcgencmd measure_volts <id>
Shows voltage. id can be one of core, sdram_c, sdram_i, sdram_p, and defaults to core if not specified.
root@raspberrypi:~# \ > for id in core sdram_c sdram_i sdram_p ; do \ > echo -e "$id:\t$(vcgencmd measure_volts $id)" ; \ > done core: volt=1.20V sdram_c: volt=1.20V sdram_i: volt=1.20V sdram_p: volt=1.23V
vcgencmd measure_temp
