The smallest, but most popular, PICAXE microcontroller. Very popular in education due to its low cost and small size, but also very popular in a wide range of hobbyist projects. Small but perfectly formed.

This chip supports up to 6 inputs/outputs with 3 analogue/touch sensor channels.

All M2 series parts support enhanced features such as configurable i/o pins, parallel tasks, ring tone music and touch sensor inputs.
