They come fully assembled, so you can rip it out of the package and drop it straight into your solderless breadboard to get started.
This version, despite being significantly smaller is actually just as capable as the old version, and still supports custom voltages if you need them. They can also be sourced without any connectors or pins installed, if you are using them for a permanent install. Best to contact Nicegear if you'd like those options.
And for those of you looking for a way to power your Arduino from a higher voltage source, check out our Wide DC Supply Shield Kit which makes it easy and safe to use a DC input between 9 and 37V DC. No excessive heat or exploding capacitors on your Arduino!
