The PICAXE-28X1 is powerful, but how about being powerful AND tiny? Here's the surface-mount version!
Exactly like the PICAXE-28X1, this the tiny SOIC 300mil version, suitable for surface mount (tiny robots!) projects.
The PICAXE-28X1 is a new revision of the popular 28 series, with way more memory, many more I/O, and supporting I2C! Now you're working with a pretty powerful micro, and still not having to crack a book on "C" programming!
The PICAXE system is a powerful, low cost microcontroller programming system designed to simplify educational and hobbyist use of microcontrollers. PICAXE chips can be programmed in a graphical 'flow-chart' environment or in easy to understand BASIC.
The PICAXE-28X1 features:
Memory (lines) = Approximate number of lines of program code the chip can hold.
Data Memory = Bytes of EEPROM memory on board (128-Prog means 128 Bytes less the space needed for your program. 256+I2C means 256 Bytes + any external EEPROM space you add via the I2C interface).
Polled Interrupt = A process that automatically checks a pin in between each command to see if something has happened (very useful!)
