PCBway has an Arduino Mega file online in Eagle - [1]. Eagle to KiCad Conversion appears to be doable. An order of 100 boards appears to be $83 - so under a dollar per board.
Cost
At $10 or $11 - the Mega chip is expensive, reportedly 50% more than the comparable pic24f. Why? Good old capitalism. [2]
At such cost, the case for DIY production is minimal. However, if the chip can be reused and recycled, there is a strong case for Design-for-Disassembly savings.
Power Draw
- About 1/2W with no peripherals - [3]
