One other thing I found out, is that some ESP32 boards sometimes are having problems being programmed when the display is attached.
In the end it manages it, but only after 5 or 6 tries. When the ESP32 is detached from the PCB it is being programmed in one try.
Probably a power issue. (or I'm using a bad USB cable)

it turns out to be the photo resistor. When I cover up this sensor it is being programmed in one try every time.
It doesn't like the bypass I made, so I interrupted the trace to GPIO2 and all is OK now.

Especially to me as I have no knowledge of totally mystifying electronics.
Well done Bob, your perseverance in fault finding is a credit to you.

Same here. I know that if you let all the smoke out, they generally stop working, but that's pretty much the extent of my knowledge.

So what do we have so far: See picture and video below.
Things that are still to be delivered are the USB cables, cigar lighter chargers and 3D prints.
Probably the shipping might take place sooner than earlier suggested.

startup screen of the device. This is my prototype, other 3D prints will look better.

Recently I was working on a manual,
you can download it here.
There's also some news in there about the 5.0 models (retrieving additional data from the OBD port).
Add a note here if some things are not clear.
Today the 3D prints are due to be delivered ...

That's not up to me, is it?
By the way, I changed the pdf already, removed the info about not needing the PTC poly fuse. It may not be neccesary, but doesn't harm either.
Since the examples in this pdf has an updated PCB, the ones I'm sending out will have a PTC like this one integrated (so not the RUSBF075)

Some delay
I took a closer look at the 3D prints,
turns out the lids of the enclosures are not printed up to my standards.
I contacted them, and they will re-print the lids (in a different orientation).
This will add 1 week to the project ...

I assume this gadget will work seamlessly without the need to turn it on or connect it via bluetooth every time one starts the car. I also assume the user can select what to monitor for the upper and lower gauge (dependent on what is available for the year). I would prefer to have volts and coolant to check. Although I would like to be able to switch to gear box which is available for 2014. I currently use the torque app connected to an ELM327 and it's a PITA. I'd rather pay a bit extra for quality parts and a factory look so there is no messing around. This is a a very useful and clever gadget. Kudos for the design and location selection. We're all going to be rocking a Cabrio Bob gadget soon in our Jag's soon.
DGL your post sneaked through without a reply from me.
- Yes it will auto connect every time you get in the car (when you start your car)
- The display will show only one item, and the button press will show the next item.
- The button also has a 2nd function, a long press (>0.5 sec.) will bring it back to the coolant temperature display (or programmed to your preference ... by yourself).
- 5.0 models will have extended data readout. Someone has to check if this works because I don't own one.
- It is recommended to disconnect the ELM327 from your car if you're not going to drive it for a while.
P.s. I'm setting up a website for the "Jaguar X150 Ashtray OBD2 Display": click me
In the future it will contain firmware updates, a manual (already available), and (links to) downloads needed to create one by yourself.

in Torque you can check the OBD protocol.

What a fantastic thread. To actually see a project from the idea stage through to completed product on a members forum is teriffic. Posters like Cabrio Bob are what make this place such a great resourse.
