I’ve been testing some Sleepy Pi prototype boards and am just about to order some next revision boards.
I’d like to offer some of this batch of boards to the community to test / use and generate some valuable feedback.
The Sleepy Pi is essentially a Smart Power Management board for the Raspberry Pi that includes a low power Arduino that stays powered when the Raspberry Pi is off. In this way it can reduce the overall power used by the RPi, particularly when powered from batteries in applications where the RPi doesn’t need to be on all the time. You can think of it as adding a “Sleep” mode to the Raspberry Pi, because the Arduino can periodically wake the RPi up to perform a task and then put it back to sleep. As a side benefit you also get some Arduino I/O to play with, like Analogue Inputs and PWM’s.
Key benefits include:
- - Reduce the effective Power consumption of the Raspberry Pi
- Power directly from batteries up to 17V
- Adds Arduino I/O to the Raspberry Pi such as Analogue In or PWM
- Break out the Raspberry Pi GPIO & Arduino I/O to screw terminals
- Prototyping area and expansion headers for daughter boards
- Power button for manual switch on/off
- “Wake” or “Sleep” in response to events or triggers such as:
- - Analogue value crosses a threshold
- Digital input changes
- Specific time to “wake” via Real-time Clock
