PreenFM > preenfm2 and preenfm3

possibility of obtaining a new pcb? or schematic?

(1/2) > >>

kirkwood:
I totally borked my build of the preenFM2. I had soldered the 22uF and 220uF capacitors in backwards. I plugged it in, obviously didn't work. Double checked my work and re-installed them.

The second time I installed them in the wrong spots. Correct polarity but swapped the 22uF with the 220uF. I plugged it in to see if it would work... then double checked everything and realized my error.

Third times a charm right? Then upon removing them again the pads are gone, no where to solder into...

I'm wondering about a couple things.

1. Did I blow up any components?
2. Is there a schematic? i could possibly run jumpers...
3. What would it take to acquire a new pcb?

lokki:
schematic is here:

https://github.com/Ixox/preenfm2/tree/master/hardware/preenF405

yeah, jumpers should be possible.

Xavier:
Lokki, this is the preenF405 schema, aka the MCU/CPU board  ;)

Kirkwood, I still have to put the PCB in the github repository.
In the meantime you can download it from the download page on the preenfm2 site.
Here is the PCB dirrect download link :
https://www.dropbox.com/s/7k68bagutq6ri52/PreenFM2_R5c_Kicad.tgz?dl=1
You'll need kicad (http://kicad-pcb.org/) to load the project.

I attached a png that may help you.
Jumpers should work.

I don't think you can have broken anything.

lokki:
haha true, sorry!!

kirkwood:
wicked. thank you so much Lokki! The pcb png is a big help. I will try manually jumping these pads, hopefully next week.
