I want to propose you the idea of a separate programmer for the Freescale CPU, I designed the above block following the schematic of Teensy 3.1 at the pjrc.com website. I divided the Teensy 3.1 in 2 blocks, programmer and CPU.

Possible benefits:

• To reduce the costs in case you want to have multiple IOTsatcom, you just need one programmer for all of them, in this case IOTsatcom will keep just the Freescale CPU onboard.

• Simplification of the IOTsatcom PCB, an easier board to be more reliable and solid dropping the USB interface and programmer on each board.

Let me know if this idea could be interesting for you and you think this is a necessary feature for the project.

Thank you.
