These little chips are like miniature SSD drives for your electronics. When you don’t need something with as much storage as a micro SD card, but an EEPROM is too small, SPI (or QSPI) Flash chips give you on-the-order-of megabytes, with little cost and complexity. Adafruit use these chips all the time on Adafruit’s CircuitPython boards to let folks store code and assets like animations, fonts, images, configurations, audio clips, etc! A great way to add datalogging storage as well.
Welcome to the world of Surface Mount Technology, Pix
If you’ve done some miles soldering through-hole parts, an 8-pin SOIC isn’t so bad.
You have a couple options:
1. High skill, can do right now, delicate.
Solder breakout wires onto the SOIC package and connect to 0.1" (2.54mm) headers to expand the chip so you can connect it to standard protoboard / breadboard
2. Lower skill, flexible prototyping purchase
We designed an SMT Protoboard that is perfect for these kinds of devices
Hi @Michael
Thanks for taking the time to help answer my question
Hope you had a lovely Christmas
I had looked at this when I was browsing around. I don’t quite know what I’m looking at yet.
It looks like every hole is connected to every other hole by gold platting?
What’s stopping infinite short circuits?
I think this is a miniature version of that stuff with tracks on both sides at 90 degrees to each other, where you tickle some of the holes with a drillbit to carve out your circuit.
…Actually nah, now I look at the vid, this board just provides extensions for little SMD pads so you can connect hookup wire. The holes only connect front to back, not to each other.
Seems so; I think the point is just to give you something to solder SMDs to that you can also solder wires to. I can totally understand why it has become a thing.
There was also talk in the vid about the ground plane which surrounds all the through-holes on the back, something-something high frequency something-something
That’s correct guys - the front side provides SMT pads that can help break-out the pins of an SMT device. you can connect the pads to standard through-holes.
The back side is essentially a “ground pour” which means you can connect your ground to the plane and distribute it easily to other points on the board.
It’s intended to serve as a convenient breakout / prototyping platform.
(if it all seems too involved perhaps a dedicated breakout PCB like i mentioned before would be more straightforward.)
