The Pi Zero W Budget Pack is almost everything you need to get going with your WiFi-enabled Pi Zero W and make it a complete meal.
This pack includes:
We also strongly recommend some other parts and pieces to make your Pi Zero computing experience easier (THESE ARE NOT INCLUDED!)
USB Console cable - if you're not going to stick an HDMI monitor on there, then this is essential, you connect the wires to the GPIO pins and log in over a serial console. Its the easiest & fastest way to get on your Pi
USB Powered Hub - So you can plug in any kind of USB devices without overloading the Zero's power supply. (You can also, ironically, power the Zero from the hub itself by plugging in a micro USB cable into the hub)
T-Cobbler - When paired with the male or female 2x20 pin header, you can use your Zero with a breadboard to connect sensors, LEDs, motors and more!
