BOM, schematic #2

Open bootstrap18 opened 10 years ago

bootstrap18 commented 10 years ago

G'day Zapta. Keen to get in on this project, help where I can. I have ordered a set of the linbus analyser rev A boards from oshpark, these have just shipped out. When you're able to can you provide a bill of materials or a schematic so I can get the components and put something together. Doesn't need to be flash :)

If you'd like to email me, bootstrap18@hotmail.com

Cheers, and all the best.

EDIT: I found the schematic for the analyser, got enough info on there

Hi Bootstrap,

The schematic and BOM are available here https://github.com/zapta/linbus/tree/master/analyzer/eagle , with the original Eagle files.

Once you build it you will need to program the firmware once via ICSP, and later you can use the Arduino IDE (it behaves like a Arduino Mini Pro 16Mhz 5V). Firmware is here https://github.com/zapta/linbus/tree/master/analyzer/firmware .

The firmware was compiled for 19,200 bps linbus with checksum V2. If yours is different change the file custom_defs.h and recompile (you will need to install the standard Arduino IDE).

Let me know if you have any question.

Components ordered, I got enough to build 3x Analysers and 3x Injectors.

The BOM is excellent, but I did find 1 error. The Digikey part number for the 0.1 uF cap (399-1179-1-ND) points to a 1.5 pF part. The part I ordered was 1276-1007-1-ND.

I checked all the other parts for potentially cheaper options, there were 1 or 2 but nothing major. I also ordered the LEDs from Digikey (parts# 754-1142-1-ND, 754-1141-1-ND, 754-1145-1-ND), but the sparkfun ones are better for about the same price.

Great job, thanks for making it super easy.

Thanks Bootstrap, I will take a look at the bom and will fix.

If you want to explore the bus with the analyzer, the serial dump utility is very useful because it has a diff mode that prints only changed bits.

If you have any question let me know.

I just fixed the bom. This is the part number I used

http://www.digikey.com/product-detail/en/C0805C104K5RACTU/399-1170-1-ND/411445

Thanks for letting me know.

Where can I find the schematic and BOM for the injector?

zapta commented 9 years ago

The eagle and pdf files are here

https://github.com/zapta/linbus/tree/master/injector/eagle

I don't have a BOM but if you have questions about specific parts I can find the digikey part numbers from my purchase orders.

Would it be too much to ask for a complete BOM? I apologize if that's an inconvenience.

zapta commented 9 years ago

Here is a BOM for a similar linbus board that shares many components with the injector. If there are parts that you don't find, let me know and I will look up.

https://github.com/zapta/linbus/blob/master/analyzer/eagle/analyzer_bom.csv

Sorry, I don't have the time now to create a complete BOM.
