A Nerdlet is the smaller, rounder, slightly simpler sibling of a Nerdling: no arms, possibly no tongue, and just one eye. Think of them as Nerdlings who have not quite grown into themselves yet.
I make each Nerdlet by hand from polymer clay in my Madison studio. They take less time than a full Nerdling, which means they tend to be a friendlier price and a good first creature if you are just starting to collect.
A few common questions

Small, a bit smaller and rounder than a Nerdling, and easy to tuck on a shelf or a desk.
Nerdlet or Nerdling?
A Nerdling has more detail and personality built in. A Nerdlet is simpler and rounder. People often start with one and end up with both.
