PICAXE-08M2 microcontroller

Product Details

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.

Revision History

Current 08M2 production firmware is version 4.A Known Issues: ISSUE - PAUSE DOES NOT WORK CORRECTLY DURING INTERRUPT ON A MULTI-TASK PROGRAM To workaround this issue use the command 'pause_int' instead of 'pause' within an interrupt in a multi (parallel) task program. Single task programs work correctly.
