speeduino / hardware Goto Github PK

Hello, I just noticed that a resistor is missing on the kicad version before the ignition output on the 0.4.3d file
While this resistance is on all the other files as well on the 0.3x 0.4x fritzing as the kicad CMS.
Is this normal? I can fix it and do a pullrequest on GitHub if you want it

I can see that 0.4.3d has C19 22uf in "Reset protection". It is
FA22X7R1E226MRU06 and pretty expensive. According to AVR040 4.7nf should be used for reset pin protection . Actually previous version of speeduino used 4.7nf instead of 22uf. Is there a need to have there such "big" capacitor?

hello, there is not an error on the pins named between the ic igni 1 & 2 has the pins of the arduino on the board 0.43 ?

Hi @noisymime,

I'm sharing the speeduino project on my own open vehicle electronics project (I'm starting with Volvo MKII platform)

https://github.com/aeonSolutions/AeonLabs-AI-Volvo-MKII-Open-Hardware

I could not find the 0.3 pdf schematic, had to download fritzing to export. Do not wish this experience upon my worst enemy. Anyways here's the schematic for 0.3.

schematic v0.3.7_schem.pdf

In project gerber Board Outline (gml/gko/gbr) file is missing. Could you please provide these?

Latest one I see is v1.2. I know there’s a 1.3 and maybe a revision of 1.3 out there.

Can you upload the .csv file from kicad instead of .pos for more convenient use

Hello guys,

Some parts in the v0.4.4.d BoM are obsolete and we need an update:

C6 C12 C13 C14 C7 C5 = Samsung | CL21B224KOCNNNC | 0.22uF SMD Capacitor - https://www.digikey.com/product-detail/en/samsung-electro-mechanics-america-inc/CL21B224KOCNNNC/1276-1284-1-ND/3889370

U1 U3 U7 U9 = STMicro | VNLD5090-E | PWR DRIVER - https://www.digikey.com.au/products/en?keywords=VNLD5090-E

Could you please update, or inform a direct substitute? Thanks in advance!

Please ensure each hardware version has viewable/printable schematics and PCB images for user reference, troubleshooting, modifications and wiring, without requiring a special program to view. Thanks!

It was noted that atmega2560 hardware SPI (PB0-3) pins (arduino mega D50-D53) are used by non SPI functions (clutch input, ignition 3 output, ignition 4 output). Perhaps these circuits could be moved to other outputs to not restrict SPI usage.

Is there Pick and place file available for the recently added SMD variant of the board?
