Hi stanley, I would like to improve my solution with your OBD-II adapter to work with electric cars. I know that this adapter actually doesn't support those new CAN protocol used in some electric cars. Are you planing to make HW/SW update to support electric cars? Or could you provide some knowledge...

Sorry for not responding a longer time. It doesn't have any impact, current is on the same level. I also open the adapter to check circuit board and everything seems fine to me. Maybe there is some hidden problem. Currently i don't have more time to investigate the cause. We have other properly work...

There is probably small current but I tested it without convertor and the result is on the attached photos. It's even worse
After I pluged the convertor it woke up and after 30 s the current fell down to 12.4 mA.
It's really strange behavior.

Connected board on the photo is just UART-USB convertor (ftdi232). It has power from laptop.
There is only RX,TX and GND wire connected.

I use a laboratory power supply set to 12V. I have a multimeter in series on the positive wire as you can see on attached photo. Meanwhile, I tried other 4 adapters and I find out that's probably issue of this one. (The adapter is just connected to an UART<->USB adapter) Is there something what shou...

Hello, I recently bought an OBD-II UART Adapter V1 and I succesfully reading data with my code and device. I would like to leave it in a car even I am not using it, so I tried to focus on power consumption and send a "ATLP" command. But the consumption is about 12mA . According to your pag...
