The power connector of the carrier board of the Nvidia Jetson TX1 is really solid and well done, but the strong vibration of a tracked robot can compromise its stability, so I decided to modify it to be sure that MyzharBot-v4 has a really robust power connection.
The first step is to solder two cables under the power connector of the carrier board of the Nvidia Jetson TX1 module. Under the power connector we can find 5 pins: the central bottom is V+, all the other are GND. I decided to solder the GND cable using two external pins:
We can use the two holes of the antennas older as cable keeper since I removed the antennas to mount them on the chassis of the robot:
To connect the board to the power source, we can use a XT60 connector, really robust to shock and vibrations. Let’s isolate the soldering pins using two shrink tubes:
Finally using hot glue we isolate and make more robust the soldering under the carrier board. When the glue is cold we can use a cutter to make it a little bit nice:
Finally we can use a little piece of Plexiglas and 3M Dual Lock to make the micro USB OTG connector a little bit more solid:
A big THANK YOU to Mauro Soligo that made a similar hack for the power connector of the Nvidia Jetson TK1 for its robot Plutarco
