Once in a While

I run into something remarkable. While I realize that I "Probably" have mentioned this item before, It deserves mention again. The Original AT-PA board from Inside Gadgets got better. The designer made some real improvements to a board with sockets for all the Tiny's and the 328 as well. He added holes for a resonator for programming 328's and any other of the smaller chips that might need a clock to recover from bad programming. This is in addition to the crystal and capacitor holes originally provided and he added bypass cap pads under the respective IC sockets for 0805 100 nF caps. The board also comes with a power led and resistor and holes for either 6 or 10 pin headers.

Those are good all-in-one boards (I have a couple), but I've found these much more convenient for breadboarding. They don't take much breadboard space and they include ISP header, reset button, decoupling caps, and some include 16MHz crystal built-in. This eliminates a lot of the common wiring errors and mess. It let's me focus more on the project at hand.

I agree fully, The board I was commenting on is only used with my usbasp for programming. The other one I own is connected to a programming shield I made from that Adafruit tutorial. I modified my programming shield to program 2313's and 85's and it's kind of nice too. I liked and will buy all but the oscillator which is a great idea but I have 4 pin oscillators for that purpose Not counting my Arduino boards I have 4 FTDI devices and a couple of bare chips in case I get an urge to make my own and a couple of asp's.. Just in case
Funds permitting I will buy the 84, 85 and 2313 boards within the month, I've been looking for something like those boards much better than the little I've seen so far...
Thank You, Sir.

imo those boards are outrageously overpriced. one can obtain promini/nano etc pcb or breakout board that accept both qfp32 (m328) and qfp100(m64/128/2561) on ebay and aliexpress for a dollar or two. about 1/10th the cost. and $5 for a 16mhz crystal is just as ridiculous.

The first three aren't overpriced If you like to work with tiny's.. The only change I'd make would be to use stacking headers because they are... Tiny.
In giving it some more thought I might have bought the "Xtal" for a breadboard tool if I hadn't chanced on the 4 pin oscillators, 5V and TTL out ( @ $0.10 Ea. Ebay)
There is also that I'm likely going to wind up making something similar since more of what I'm really interested is 3V3 powered and there a known breadboard tool is handy for the few things that require more space and or I/O than a Tiny provides. Also that clock oscillators for 3V3 are 'slightly' more expensive than older surplus.

doc, you got a link for the 10 cent oscillators? im probably not using the right search terms but they seem to run $5 ea and no less than $1 in qty. i could really use some cheap ttl osc for t13 projects which cannot accept xtl.

10cents, including shipping would be a real find. Where's the URL ?

Here are some SMD 16 MHz Oscillators that are reasonable...

10 for 5.99, US seller and "More Than 10 Available"... This took 3 minutes... and the first page. The search term was "TTL Oscillators"

@Doc, that is a good price, but it is 600% more than you had just stated.
No worries, I don't always get it right either.

Yeah but I bought 25 of them for $3.00, 50 DL7660 7 seg displays and a bunch of other crap for $15.00 total. one of those "Grab Bag" things. One of those 'rare' finds in a pile of 20 year old crap. There were CD4094's Too. They are a super HC595 without all the Stuff.. 4 pins: data, clock, strobe, output enable.. Not as fast (1.25 MHz Vs 100 MHz clock speed @ 5V BUT 3 to 18 V Vdd and 10 mA output per pin make them a natural for driving PNP transistors directly.. Makes for a neat high side driver, without all the extra pins on the '595.
I had to pick the old original black antistatic foam from the CD4094BE pins. It fell apart as I was removing the IC's for better storage.
I shop there constantly but buy little unless I have a project for it... OR the "deal" is too good to pass up, Want to buy some LEM 300A current transformers, Hall Effect devices, Wind a few extra turns and make a 0 to 10A (30 turns of 18 Ga fits comfortably) AC or DC, I have 12 of them new in the carrier... another thing that was too good to pass up... They 'sell' for $50.00 all the places I've checked (3)...

@Doc,
Yea, that sounds like a really good find. I hope you find more like that soon.

Have a good day.

Those SMD things would make a perfect Tindie Board.. a 4 pin plug in and add a bypass cap on the Vcc line of a 328 at the same time..
