Hi, I want to take a signal of known voltage from another source and pass it through the reach m+ timing pin. Problem is I don’t know the current passing through the wire I’m going to use. If I know the voltage then I can drop a resistor in series to guarantee the maximum current. What is the maximum current I can pass to the timing pin without smoking the reach m+?
I want to use a 4v signal and limit it’s current to well below whatever the reach m+ is rated for. Does the m+ have protection circuitry if I’m using 4v instead of 3.3v?
I want to hook it straight to the LED wire of a UAV to trigger the recording of an event when the LED blinks. I think the LED circuit is about 4V but I have no idea of the current that the circuit can provide. I don’t want to smoke the Reach M+ so i’m wondering if the port has a maximum current rating. If it’s not much then perhaps I have to look at using a relay.
I read in the Reach RTK specifications that the Time Mark input has an over-voltage clamp and a current limiting resistor. Would the Reach M+ also have this kind of protection for the Time Mark 1 pin?
I may be asking the wrong question as I’m an electronics novice.
