The emonVs (a severe case of digitus erroneous or an over-enthusiastic spell-checker there) supplies 5 V d.c. and one or three 0.333 V voltage samples (depending on the version - single or 3-phase) to the emonTx4. It has sufficient current capability at 5 V d.c. to supply ancillary items, such as a Raspberry Pi incorporated in an emonBase, or the [emonPi2](https://community.openenergymonitor.org/t/avr-db-emontx-v4-new-hardware-in-progress/20209/298) (presumably with a different output cable & connector).
