Here are my gerber files for VCDS that i made long time ago

And manufactured boards:

good job 0x44 version, I probably will order a couple of boards for your gerberas, only perhaps I will replace si9200 with tja1050 and si9241 with l9637d, I will have to change the scheme a little bit, 9637 easier and cheaper for me to buy, 1050 has a built-in filter on the can-bus

What is the purpose of all this? To me all of this looks like reinventing the bike. Items available in mass production (which they are in this case) will always be cheaper than building something yourself. Will you improve something with your own design? I highly doubt that.

It’s not for money)) I don’t know what you are doing, but it’s always a pleasure for a radio amateur to collect something with his own hands and then he is very proud that it works, so it’s a goal to collect something and not to buy something ready.

aren't those pcb's more expensive than a complete cable......................

love the initiative by the way

if you want i can send you layout file for sprint layout?

Hi

Its really neccesary FT232BL with 0x44 interface ??
Its ok this schema for 0x44 interface ??

Regards

it will be very nice if you can send sprint layout file

also if you have few empty PCB i will buy

**xoom** · 11th January, 2019, 03:24 PM

4 boards left at the moment

Here is Sprint Layout5 file:

Honestly, this is not a very good scheme 0х44, I don’t understand why to put the L7812 and then a 5 volt Zener diode, it is easier to set 7805 if the Zener diode fails the ports of the laptop explode).

See ONLY pin 4 is pulled-up externaly. That make me think is used in logical as 1. pins 1 and 9 not used, so..not connected.

And another thing: the programm having a button named "OBD II". Is for generic and, as i saw work only for engine for other cars.
When i am lazzy time to time erase DTC for engine for my old Corsa 2001.
Is very possible using LLine for this "OBD generic"..
Is very possible too RT excluded the LLine support in 46 HW. I don't remember when 46 released..If someone having old installers can see in wich version appear HPxxx.bin. But this not explain why LLine circuit still exist.
Is very possible too, chineses tried extract dump or a person for them..and..extracted truncated or truncated by himself for this motive ("is old, no need")

I can't download this file, is it removed?

Elektrik1 amazing work regarding GAL chip. Thank you for your time!

i briefly checked your pcb and have one question ?

where is 22pF connected, one side is connected to OSC 7.37MHz and the other side of capacitors is in the air?

**Mrjitter** · 11th January, 2019, 03:58 PM

Hi

i put the zener component, but its a normal diode . Its for apply 5v from usb to all circuit, to program the atmega. Not neccesary 12v from OBD connector .
I have not usbasp, i have old stk500 program interface. This interface has not 5v to supply atmega.
