SMD's that many is impossible to do it manually in reasonable time and with no errors!
When production is low and you have through hole components, these are assembled by hand. And this costs......
Yes you can reuse them but you need to be careful as to what circuitry you hang off the pins.
Most ICSP programmers have 4.7K pull-down resistors on the PGC/PGD pins and assume the pins will idle...
Yup, confirmed. I removed headers from BOM and CPL and those 2 fees went away, as well as an extra $3 or so for cost of headers about $13 + tax reduction).
Anyways, I've decided to install the...
Do I have special considerations to take when I reuse ICSP pins?
Do I need a jumper during programming if I have a device connected, like a resistor/LED?
(I couldn't find any REUSE PGC/PGD/ICSP...
I'm pretty sure we get hit with "engineering", "setup" and "stencil" fees everywhere.
I tried to limit the "extended components fee" by using Basic components when possible (resistors and...
Yup, first thing I do is match all components on JLC's inventory for a given footprint and input price, JLC part # and Manufacturer part # in my symbol editor (Kicad), as well as if it's a Basic part...
Demon - 15th June 2024, 23:32We all hoped that PBP would find a way in the future but now I am convinced this will not happen.
People change, so microcontroller also do. Arduino, Pi, Python, and many many others are out...
From my experience, the chips that were in stock by JLC were double or triple the price from Mouser. The others that were not in stock were cheaper...!
But since I wanted only 20 assembled PCB's...
Yes that is very true!
Hopefully some young enthusiast buys out PBP, I'd happy to be a VC for this. Keep me posted if you do hear of anything.
Haven't got a led flashing yet....but have managed...
Re: Reusing PGC & PGD pins
I connect the ICSP port on the PCB to the ICSP pins of the controller directly. The Pins in turn go to the rest of your circuitry via resistors so that you do not need programming jumpers to perform...
