Power 03: Hibernate mode

This example shows how to set Waspmote in the lowest power consumption mode, disconnecting all the board but RTC, which powers from auxiliary battery.

Required Materials

1 x Waspmote 1 x MiniUSB wire 1 x Battery

Notes

- IMPORTANT: The first time you run this code, the Hibernate switch MUST be turned OFF before the red led lights off (3 seconds after switch Waspmote PRO ON). - This example can be executed in Waspmote v12 and Waspmote v15
