Calling all PCB designers....

I just had a thought that should make any one of you a KILLING...

Shift Registers, cheap and friendly, simply offer customers a PCB breakout board which comes with an array of shift registers, on the breakout all there will be..

5v+ Gnd Data Latch Clock

(And then unsoldered pads/holes... for each of the outs which the person at home can do themselves)

You could literally sell them using surface mounted or through hole, in boards of 2, 5, 10, you ship them off the breakout board, we as the end user get a shift breakout and then start wiring up whatever we want...

You know how much time and effort you'd be saving people with something like this?.. XD

Especially if you daisy-chained, like, 4 together.

Like this, but 1000 times neater:

Maybe an optional out then such as the unl array transistors IC's to compliment the 7hc595 to give it a bit of power boost for higher powered applications.

maybe a breakout complete with resistor/led too?

Sounds like an opportunity for a bright young lad, I'm thinking "Crossroads" :)

Maybe in modules that plug together and also have RA headers on a .1" pitch for breadboards.


Something like this you mean?

exactly not like that...

I'm thinking of 2 types to be offered, a blank board with an array of drilled holes ready to drop the chips in... or buy it complete with chips, the idea being you can link and daisychain them, that breakout board is kinda pointless.... boards with space for 5 registers or 10 registers.

"Crossroads" had this board, 12 TPIC6B595 which are high power version of the 74HC595 with output ratings of 50 V and 150-mA continuous sinkcurrent capability.

12-digit, or 96 Bit, LED driver, using TPIC6B595. Bare boards, $5. Kits, assembled boards, available upon request.

See, I told you he was the guy to do this :)


The design.....

Drop the atmega side of it and the power supply side to it.

Then having the pin of each shift register get put into seperate blocks from bottom left of the PCB..

A little re-design and this would be a perfect breakout board....

oh and have it designed for a 74hc595 … (I got heaps of them)

HC595's are pathetic for driving any kind of a load tho, 70mA/chip limit. Populate it as you see fit. I made up 5 pairs with 10 shift registers each board, the 2nd board only had the shift registers, to drive a non-multiplexed 5x20 display with it.
