[help needed] Frankenso: does anyone have pictures for this board

[bigredproject]

if anybody has pictures of a fully build board identical to mine for a NA 1994 1.8L miata please send them to me or help me build this board because my board is different from all the pictures out there

[AndreyB]

There are some pictures at https://github.com/rusefi/rusefi_documentation/tree/master/Hardware/Frankenso

Most sections of the board are pretty much the same

Also useful is interactive BOM https://rusefi.com/docs/ibom/frankenso_latest.html

what does DNP mean for value

[AndreyB]

Do Not Populate

[bigredproject]

i also was not givven enough 1uf

if i just don't have something or dont have enough what do i do

[AndreyB]

i also was not givven enough 1uf

How blocked are you by that? How many were included and how many do you need total?

[bigredproject]

can i use 4.7pf insted of 4.7uf i dont have 4.7uf

[AndreyB]

can i use 4.7pf insted of 4.7uf i dont have 4.7uf

I would not recommend since those are probably x1000 wrong? How does 4.7pf convert into uf and vise versa?

Can you please post close-ups of MAX9926 soldering? The pictures you've posted so far are raising some questions.

[bigredproject]

how does this seem?

[AndreyB]

At the moment I am concerned at least about this area. Can you please post a better picture focusing on this component exactly?

I guess that looks better now. Are you using soldering paste and hot air or some other approach?

[bigredproject]

im just using a soldering iron and solder

[Simon@FutureProof]

Have you looked at this thread?

https://rusefi.com/forum/viewtopic.php?f=4&t=1409

I also strongly recommend watching this video for some pointers on soldering the RE hardware.

Hi. Im seriously concerned with the quality of the soldering. I can see many solder bridges and misaligned chips. You really need to take your time and do it right. I dont mean this to be insulting and i hope it isnt taken this way. Is there a reason you went with this kit rather than getting the premade Hellen?

[bigredproject]

because im broke

[bigredproject]

in the picture does it look like it will blow up when i plug it in or does the front look good? for 1994 1.8l miata

[AndreyB]

Yes

Also all the components here are NOT assembled if you are planning to snap green board in.

[bigredproject]

what do i need for green board and why does it look like it will blow up

what do those mean

[AndreyB]

huh?

[bigredproject]

in the digram it says OR and OPT for some of the values

[AndreyB]

in the digram it says OR and OPT for some of the values

0R? zero ohms?

[bigredproject]

for value what would 1500 .1% be in the resistors because there is no 1500 resistor

[AndreyB]

because there is no 1500 resistor

No way.

[bigredproject]

on my sheet it shows that there is no 1500 and I looked through all of the resistors and there is no 1500 so what do I do

[AndreyB]

I am sorry but you are not qualified to assembled this kit.

[bigredproject]

wait 1.5 is 1500?

[mck1117]

p means Pico (10^-12)
n means nano (10^-9)
u means micro (10^-6)
K means thousand (10^3)
M means million (10^6)

I know it is not the prettiest but does it look finished and ready to plug into USB?
