I’ve checked the information from forum and looked through the product catalogs, but I couldn’t find a clear answer.
What is the maximum current that a single 5V output can supply before the voltage starts to drop?
Are the 5V output pins internally connected to the same power rail, or are they separate rails with individual current limits?
I’m trying to understand the safe current limits when using multiple 5V outputs at the same time.
I don’t know the exact answer to your question but there generally isn’t a hard set limit on how many sensors you can run off of one 5v supply. How many sensors are you trying to wire up?
You would need to know the resistance of every single wire and sensor to really calculate the amp draw. However like I said, you aren’t really powering anything that is a large consumer.
EDL1 is connected to the 5V pin and the voltage drops to around 4.96–4.98 V when writing to the SD card. It is affecting connected sensors
Connect EDL1 to 12v ignition switch
Yeah i moved it to 12v but I was curious about the 5v outpu
You would have to email support directly to see if they could get you an answer. Now knowing that you had the EDL1 on the circuit, I definitely would had moved it to a 12v source and power ground. If you had the EDL1 on a 5v supply all by itself, it probably would be fine. However a 12v supply and power ground would definitely be more stable. Hopefully they get back to you with an answer.
