Overview
Accidents can happen, and accidents like sudden power cuts may damage your Raspberry Pi, resulting in lost work or even potential damage to the electronics. Hence using a UPS is always important. When building a UPS, Handling multiple sources of power like a battery and a DC power source becomes difficult. We need to switch power from one source to another to ensure that there is always a smooth source of power supply going to our device, which in this case is the raspberry pi. Special thanks to our sponsor, DigiKey Electronics, for providing the components used in this project.
The process for building the project is too easy. We just need to combine the two IC’s and their associated components together in the design. Print the PCB’s and solder all the components on to it. The two main IC which we used were LTC4089-3 power path controller and LT3759 wide range power booster.
The result of all these efforts were amazing. We built and tested a Raspberry pi UPS which will be used to protect the raspberry pi from any damage due to power cuts and will give time to the user to save their data before shutting down.
