Surface mount PICAXE? You bet! All the power of the PICAXE-18X in a tiny 300mil SOIC.
Sometime, you just have to build smaller. If you love these great PICAxe chips, you'll be happy to know that the PICAxe-18X is now available as a 300mil SOIC! That means you have your 5 inputs, 8 outputs, and I2C support!
The PICAXE-18X offers:
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!)
