PIC12F are great small microcontrollers with 8 legs. They usually come with internal oscillator, 4 channels 10-bit ADC, EEPROM, voltage reference, several communication peripherals like USART, SPI, I2C, timers and other. So with it you can build quit powerful applications and control devices.
Embedded-lab introduced pretty handy development board fir this micro. It has many features that enable rapid prototyping or learning the basics. It comes with 5V voltage regulator, I/O header for all MCU pins, fairly big prototyping area, ICSP programming header, four push buttons connected to analog pin through voltage divider resistors, and couple LEDs – one power another attached to digital output. You can solder any component to prototyping area and have even more to do.
