TK1 vs TX1

[Chris_Ely]

The TX1 is newer and more powerful than the TK1. Yet, it is smaller. The computer is on a board the size of a credit card which plugs into various breakout boards that you can buy or design yourself. The TX1 ships on a mITX sized dev board, but you can get breakout boards that are the same size as it. My roommate is using a TX1 for Michigan Tech's Intelligent Ground Vehicle Competition team. I will point him to this thread to give more details.
If cost isn't an issue, the TX1 is better. It is also on FIRST Choice.

Hi,

I'm Chris's roommate from MTU. The TX1 is nice because you can get it with a carrier board that can be quite small. There is a list of boards here http://elinux.org/Jetson_TX1#Ecosystem_Products. Most of them are ok with a range of input voltage such as 5.5-19.6VDC for the carrier board that comes with the TX1, other boards may vary though. The board doesn't draw much power and is typically under 15W.
