I want to design a Power Supply Unit(PSU) for Raspbery Pi Zero W. I will have a camera https://www.raspberrypi.org/products/camera-module-v2 connected and running, two relays and few gpio's running.
Camera Consumes around 250mA, RPi idle mode 150mA.
I read here https://www.raspberrypi.org/help/faqs/#power it states Recommended PSU to be 1.2A I can design 5V 1A PSU, will it be sufficient? How to calculate power consumption?
I have read these before but still unclear
If not, could you please share some PSU reference design with inrush | surge protection for 1.2A?
