The venerable ESP8266, in an Arduino form factor. I've linked these before but they're getting cheaper and cheaper, and are massively handy. If you aren't `in the know`, these things are like an arduino, work with arduino shields, even with the arduino software, but are 10x faster, 32-bit instead of 8-bit, have 4MB of flash storage, and native WiFi internet capabilities! Definitely the modern replacement and a great way to get started.

The STM32 is another handy microcontroller. Running at 72MHz with 32-bits of processing power, it provides far better Analog to Digital and interface capabilities, but lacks the native WiFi networking. Again can be used with the Arduino IDE, or another great use is http://tomeko.net/miniscope_v2c/ - an entry level USB oscilloscope (2 channel x 460kSPS) for under $2.

These connectors will fit directly into breadboards, and provide an easy way to attach random bare wires. It's worth noting here that most breadboards can only handle around 1A of current, so be careful about connecting stuff up to your board, unless you want things to get... melty.

This thing found its way into my shopping list as a way to use the left over stepper driver modules from my 3D printer, after upgrading them. A cheap little arduino shield that can be used to create a 4 axis engraver or printer.
