I have been tempted by the Nano board recently, having not given it much consideration before.
Though yesterday I discovered that the Micro has almost an identical spec sheet, with more usable GPIO pins and a Micro-USB connection, while maintaining a similar sized footprint.
The Micro uses a 32u4, whereas the Nano uses the 328 chip. Are there any disadvantages to the 32u4 of the Micro, when compared to the 328?
If not, why would someone choose the Nano over the Micro?
Thanks in advance for your help.
