| 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. | |
