Just out of interest what are the dimensions of these two versions of boards? I am interested to see how much they would cost to have made?????

[dvjcodec]

Rev.A - 103x80mm
Rev.B - 165x118mm

Rev a is not too bad , I was a bit worried over the 103 but it goes through as £20gbp with allpcb, but the ReV b jumps up to 44gbp again from allpcb.
Both are on a DHL 8 day service

Also this is for 10 boards.


So overall not too bad

Even on the revb I'm not sure I would put ignition drivers in the case... I would have suggested upping the injector outs to 8 Ch and low level ignition to 8ch and perhaps some extra ancillary outs??? The teensy will be able to use them all soon I'm sure, especially if a board supports it
Good work ..

what software are you using to design your boards and 3d renders?

[dvjcodec]

Rev. A is OK to me, but when look for a enclusure and connectors, everything was expensive. Rev. B is almost same like A (except passive coils drivers and diagnostic led's), but fit into cheap enclosure, what is important to me.

Renders I make with Goole Sketchup. Use plugin EagleUp for Eagle and Sketchup.

Add 4 injectrors more and 4 ignitions (active) more sounds good. Have free place for it.

It grows

All traces completed

Do you have revA board for sale ? I'm very interested in building it for my car and I can't find a place that make just 1 or 2 PCB cheap ...

[dvjcodec]

Not yet. Waiting for PCB's from china manufacturer. Do U check allpcb.com? I was pay extra for TNT shipping to Poland + customs (probably). Ordered 10 pieces.

Rev.B on Github with last PCB modyfications :
- few traces redesigned
- add I2C to external
- add vias for Teensy inside pads
- add UD+/UD- from Teensy to external
