Motherboard test program

This simple test program will demonstrate that the 20M2 microcontroller is functioning. Shortly after download the Terminal display will appear and show a message indicating the 20M2 is working.

Code Example:
#picaxe 20M2
#terminal 4800

	pause 2000
main:	sertxd( "I'm your 20M2 microcontroller", cr, lf )
	pause 1000
	goto main

Create Module

No 20M2 Motherboard is available for the create system at present, however a suitable alternative for moving 'robot' style projects is the BOT120 motherboard kit (based around the PICAXE-20X2 microcontroller) and for non-mobile circuits the 18M2 Motherboard (based around the PICAXE-18M2 microcontroller).
