PICAXE Chip Labels
The name engraved on the top of the PICAXE chip tells you which type of chip it is. You can also do a 'firmware check' within the PICAXE software to identify the type and version of chip connected.
The M2 series chips are engraved with the full PICAXE name**, whilst other parts are simply marked with the base Microchip 'PIC' name. See the table below for the names engraved on the current PICAXE parts.
** M2 surface mount parts (and in times of supply shortages, DIP parts) may also be supplied marked with just the standard base Microchip 'PIC' name.

The ‘advanced technical’ datasheet link below is for those users who want to know the advanced operating characteristics of the base PIC microcontroller. This information is not required for normal PICAXE use - see the PICAXE manuals instead.
