I was looking at the schematics, and I noticed that it has 6 GPIO ports that are tied to 12V drivers, and are fused at 750 mA. I was curious to see if this would be enough to power a small dashcam (Street Guardian SG9665GC). I currently have it plugged into the accessory 12V port using the included adapter which steps the voltage down to 5V (USB power level). I doubt it’s even pulling 500 mA at 5V, so it should pull even less at 12V.
The safest thing I could do would be to connect a relay, but if the M2 can power it directly, that would be a lot simpler.
