Tinkering Kit
While the power-efcient C2 is a very capable system for soft-
ware development, it is also very highly suited to prototyping hardware
development. Hardkernel has developed the C Tinkering kit with nu-
merous items to get you started, as shown on the next page.
Some of the components in the Tinkering Kit include:
• Assembled T-breakout PCB - 40Pin GPIO Breakout board
• Breadboard - 630 Tie-points with dual power lanes
• 40pin Ribbon cable - IDC Flat cable 100mm
