We just designed our low cost programmer with mini USB connector! It is basically a USB to TTL serial converter with DTR signal that drives the RESET of our modules using a simple IRLM6402 Fet.
It means you can download firmware from your computer without any action on Reset buttons and during development you can save hundreds of pushbutton pressions!
So on the Nest and miniNest boards will be now present a FTDI chip. On all these boards will be present a 6 ways p.254mm connector that fits this new miniUSB PROGRAMMER.
