| Description |
| ----------- |
| |
| Lochnagar 2 features built-in Current Monitor circuitry that allows for the |
| measurement of both voltage and current on up to eight of the supply voltage |
| rails provided to the minicards. The Current Monitor does not require any |
| hardware modifications or external circuitry to operate. |
| |
| The current and voltage measurements are obtained through the standard register |
| map interface to the Lochnagar board controller, and can therefore be monitored |
| by software. |
