Never bother with the pin marking as it could be one or another.
Been trying to work out how to make an adapter pcb that can accept two different displays. Realised that they use the same interface so I can just fit a header…
this is a dumbass rescue mission… i keep telling myself:
Imagine your precious new module arrived and you are eager to try it… caution? yaeh I’m allways carefull. you connect your module to your self built bus board where you used singel pin rows instead of propper connectors with red markings and targeting help, it’s the workbench, it’ll do…
and suddenly your brand new module emmits magic smoke and dies
I think it is only this smd-component but what was it? any suggestion?
i did not turn the cable but i must have been one row off center to the left or right. the module expected +5V…
It’s definitely a transistor or regulator of some kind; the footprint is SOT-23-5. I’m having trouble finding codes that match what appears to be printed on the chip. Can you make it out any better in person? What module is it?
What module is it?
it is a Mordax Data. LOVE the quote. i probably would not have found it without the incedent and did not make the conection form (info)data to person Data before seeing it.
Can you make it out any better in person?
I made multiple pictures, my poor eyes see only the tiny component itself. I think it says KAGRBO, but on the last three letters I am not sure. the affected area is in the top left corner on the upper picture
(edit:left<>right)
It looks like it might be the KA78M05R (KA05R on the IC?).
Sending the pics to the manufacturer ?
It’s the person in the know…
I have a “contact form” running…
It looks to me like KA_RB_ something. The second character looks like it might be a C, G, or 0. I can’t make out the last one, though.
Oof! Remember to always put in all ICs before first power-up, especially the rare ones
Not something I would usually do… but I’ve got so much to do I’ve been trying to batch out jobs.
So the other day I was like ‘might as well put the ICs in all the boards so they’re ready’.
I have double checked all the other boards and only seem to have made that mistake once. Still… will be pulling all the ICs back out of the rest just in case.
EnvGens currently on back order too…
We’ve all been there…
Aww man… That’s a bummer.
I’ve got to say, my first thought when I looked at the schematic was, “Is that a 5v plane? Weird choice, but ok, I guess.”
It’s amazing how use of a cheap multimeter can save you enough money to buy an expensive multimeter.
OMG my mind just connected the dots… I know why they’re called IDC connectors now! Wow, do I feel stupid.
“That’s a dumb connector.” “I Don’t Care.”
I flasshed all my own EnvGen’s , and vclfos…
As AO says , a multimeter saves all the heart ache…
Oh, how do you flash your own envgens?
Buy a plain, PIC 16F1764 download the hex file from above, get a PICKIT3 and write to the chip.
The supply of chips was low last year but I was able to get them from DIGIKEY last year.
