I need help on how to wire the logic converter.
I am trying to use a laser range finder that work with 3.3 V with pixhawk flight controller which work with 5V. So if I connect the laser directly it will be burned and damaged.
So I bought the SparkFun Logic Level Converter - Single Supply
Now correct me if I am wrong.
it looks like the power wire from pixhawk goes to vin 3-5 voltage and gnd below it. Then vout 3.3 and gnd to the laser.
But what about the TX and RX ? How do I wire those ?
Thank you
