A word of caution with the Cortex Pro.

Due to the case and circuit board design, it is very easy to mis-pin the 3 connectors next to the bind socket.

Internally to the gyro, it appears that the +ve and -ve power lines are shared across all connectors, so by mis-pinning one of the connectors that are used to supply power to the gyro (such as when using a dual bus configuration from Jeti) you end up shorting out the power supply to the gyro.

I burned up and destroyed a Jeti CB200 by inadvertently mis-pinning the gyro. The CB200 showed that I drew over 28A and burned it out. It has taken me a while to figure out how I did it, but luckily I found it when I didn't have the CB200 powered up, otherwise the replacement CB200 would have suffered the same fate.

A simple design error that cost me a $200 CB200.

I would recommend that the case and/ or circuit board be redesigned to prevent a mis-pinning of the 3 sockets adjacent to the bind socket.
