The tink fit into the r3 case. For general programming, I'm not noticing any heat. If you were setting this up as a streaming box, then you might need a little fan. But I would just use a generic android tv box, since they produce those by the billion, and a fan is ridiculous.
The real reason for this type of board is the connection with other things. Here, I am using 4 pins to connect with my adxl355 breakout board. The 355 and 345 came out at the same time, but the 355 is the space-age expensive one, meant for more scientific things. You don't read much about it. The 345 with 16 bits is a tiny fraction of the cost. That's why I was looking at putting a bunch of them together in an array, but that was cumbersome.
I've gotten the I2C working, and now I am programming the registers. Luckily I found a Python driver, and I'm learning more Python. What a great hobby for an old man. :)
