RTk.GPIO Adapter - USB Raspberry Pi Compatible GPIO Header

Sat Apr 30, 2016 9:42 am

Ryan Walmsley has come up with a cracking product - a USB device that can be plugged into any computer to let you use Raspberry PI Add-on boards without a Raspberry Pi!

Its up to 80% funded - just another £1000 needed to make it a go-er!

I know Pi Zeros are in short supply but don't they do more for less?

PiZeros are funny. I can't get hold of them to sell and from what I can tell there's no profit involved (No company can sell stuff without profit hence the need to bundle them with lots of add-ons and also made apparent that a cable to connect a camera also costs £4).

It kinda targets a different market as it works purely like a GPIO header. With a Pi zero you've got to add extra software and it wouldn't quite be as real time as this is.

Finally price is about the same at £10. Pi zero costs £4-5, SD card at £4-5. Add-on a header which isn't pre soldered and you're there.

I see this board as a very useful one to use in schools.

The Pi itself is quite hard to use in classrooms (unless you've got a computer suite and can use PiNet)

If the GPIO.Zero library can be be forked so that it runs on a classroom laptop, then all the Python teaching material being developed for it could be used on this board without all the cost and complication of using a Pi3.

But the skills learnt are then 100% transferable to running same code on a standalone Pi

The same philosophy could be applied to NuScratch so that Scratch code running on classroom computer runs the hardware add-ons on the RTk.GPIO adaptor.

Remember that the pigpio Python module should run on Windows/Macs/Linux, in fact it should run on anything which supports Python.

I think NuScratch is bound to the Pi, but GPIO Zero should work with a pigpio back-end.
