Alternative Turtle Rover hat rev. I

I had to make a new iteration of my alternative electronics hat for the Turtle Rover. On the former revision G I run into trouble with external I2C due to level shifting issues. Took the chance to simplify the circuit and route I2C and RS232 directly to the Raspberry Pi header instead through ARM micro-controller. So the server software can directly access any external peripherals through kernel drivers. Hardware description available on Github.

In addition I created a experimental motor driver board with dual ST L6206 DMOS full bridge driver as a direct drop-in replacement for the L298.

Dear Finland

…in a war with Russia you will not have GPS at all, so stop whining. Even when we consider that  Russia is the reason for your GPS problem, then I am pretty sure that someone was just playing with the jammer. You have not even experienced half of the equipment capability. Or someone just spent 120€ for an ADALM-PLUTO and tried pluto-gps-sim

However, NATO must be doomed when they can not run a war without GPS.
