Thank you for your kind reply and assurances about the power supply requirements. I hope that you can connect this board to the RPi Zero Wireless A GPIO board such as the PIFACE PIFACE DIGITAL 2 I/O Expansion Board for Raspberry Pi B+.A wired usb keyboard connected to a usb hub - connected many other dievies eg a usb camera.A 5V 1000mA supply connected to the right-most usb hub.A wired wired usb keyboard connected to a usb hub - connect many other devices.Hub is connected to the right most micro usb. A powered usb hub - provide power and connect many usb devices.A wired usb keyboard with a usb to micro-usb converter.

This is my intention to connect the following peripherals: I happen to have a 1A (1000mA) 5V supply with a micro usb and hope to use that supply with my RPi Wireless Zero. It would be definitely less than the power consumption of much bigger Model B. Nevertheless, I would like to know the power consumption of the RPi Wireless. I know you sell a 5V supply with a micro usb which is 2.5A. I would like to know the power consumption of the RPi Wireless zero.
