Cost: $10.95 each
Description: The PICAXE X2 microcontrollers are the second generation of PICAXE chips; providing more features and greater flexibility. With the PICAXE 40x2, you get four times the memory and a number of additional input and output pins, when compared to the 40x1.
PICAXE is a neat entry-level microcontroller system that is relatively cheap to get started with. The chip is programmed with a simple serial connection and the BASIC development environment is free! PICAXE has some excellent educational applications and support, and is a great entryway into more complicated embedded systems. If you're look for a place to start with microcontrollers, PICAXE is a great way to go!
