| Aug 6, 2017 at 8:16 | comment | added | Rustie0125 | No!The Power input on the pi from external power source is 5v. the GPIO pins are only 3v3 capable. the inputs from the external circuits to the PI's GPIO pins needs to be converted | |
| Aug 5, 2017 at 5:06 | comment | added | Jason Han | But the Pi not able to accept 5V, right? Is there an LDO that step down to 3V3 somewhere on the board? | |
| Aug 5, 2017 at 3:55 | comment | added | Rustie0125 | I dont supply the pi with 3v3 only 5v. | |
| Aug 4, 2017 at 15:30 | comment | added | Jason Han | 3V3 is the supply to your PI. After the LDO as shown in the first picture. 3V7 is the Lipo battery. | |
| Aug 4, 2017 at 15:17 | comment | added | Rustie0125 | Hi Jason Looked at your diagram but not 100% of its integration. why do you have multiple voltage now ? the control and 5v makes sense but are you refering to battery level by 3v3 input ? | |
| Aug 3, 2017 at 7:36 | comment | added | Dmitry Grigoryev | Note that you need to disconnect the battery from the RPi after a shutdown (e.g. using a MOSFET), otherwise it will still drain 0.2A even in shutdown state. | |

| Aug 3, 2017 at 4:45 | comment | added | Rustie0125 | Yes that is where the battery voltage is measured | |
| Aug 2, 2017 at 4:53 | comment | added | Jason Han | Add a diagram. Is it what you have for your supplies? | |

| Aug 2, 2017 at 4:16 | comment | added | Rustie0125 | Hope my alteration makes sense | |
| Aug 1, 2017 at 9:28 | comment | added | Jason Han | My bad. Use the fruit to send a 5V signal to control this circuit and it should work without the MCU (Arduino). | |
| Aug 1, 2017 at 9:21 | comment | added | Rustie0125 | Are you refereeing to the Pi or the Arduino as MCU ? the purpose of the questions is to get rid of the arduino all together | |
| Aug 1, 2017 at 8:22 | comment | added | Jason Han | When the MCU detect a low voltage and you send a command to shutdown, set your "Control" pin as input. In other normal working conditions; both mains and battery power, it should set as output high. | |
| Aug 1, 2017 at 8:08 | comment | added | Rustie0125 | Thank you for the feedback, where does the battery condition come into play ? | |
