The PICAXE-40X1 IC is the biggest, baddest PICAXE made. LOTS of power, memory, and ability, all programmable in a graphical flowchart-like language or easy-to-learn BASIC.
The PICAXE-28X1 is powerful, but how about being powerful AND tiny? Here's the surface-mount version!
Looking for a more flexibility out of your Sumovore, but you're not too up on programming? The PICAXE is a PIC-based solution, programmable with flowcharts - and we've added it to the Sumovore!
