Based on the 7805 linear voltage regulator ic it provides a precise 5 0 v output no matter the load you put on the voltage rails.
Raspberry pi power supply circuit.
Unfortunately portable power banks that meet these requirements are hard to find and expensive.
We make intelligent shutdown circuits for your raspberry pi.
An uninterruptible power supply ups is a small battery combined with a clever circuit and the usual mains power.
All models require a 5 1v supply but the current supplied generally increases according to model.
It ll keep feeding your pi the steady 2 5a it needs for proper performance.
We ve tested this supply in all kinds of situations and it s as solid as a rock.
To accomplish this task i am building a raspberry pi soft power controller.
Mains power runs the pi and charges the battery.
Here s a block diagram of the power controller.
