1. Q: Which GPIO pin is used, and can I change this? A: Pin 23 is used by default. Version 1.4 (after december2016) has a jumper to set pin 11 as alternative) You further can change this by soldering one wire to another pin. 2. Q: Can I change the time from the moment power fails to shutdown initiation? A: The delay for shutdown is fixed in the firmware. Please use the contact form to submit a request to customize your device before ordering. 3. Q: Can I use a car battery or any other battery to run my Raspberry for many hours with Safe Power? A: You can use any other LiPo rechargeable battery of 3.7V at your own risk. Batteries other than 3.7V LiPo will not work or destroy the device. Safe Power is primarly designed to prevent data loss due to file system corruption.
1. Q: Do I need to install software to run Safe power? A: Yes you will need Python GPIO libraries (installed by default in raspbian), and a simple Python script which is provided with instructions here.
