RasPiO Full pHAT lets you...
- connect two pHATs to your Pi and still use spare GPIO ports
- connect a pHAT + a HAT to your Pi and still use spare GPIO ports
- break out the Pi GPIO ports multiple times with large, clear labels
...so it opens up a lot of possibilities for combining boards into a project. This photo shows a RasPiO InsPiRing driver board and a Pimoroni inkyphat on a RasPiO FullpHAT.
But even with those two pHATs in use at the same time, you still have 19 other GPIO ports unused. With RasPiO FullpHAT, you can access and use them for your projects.
Kit Contents - What do I get?
- RasPiO Full pHAT PCB
- stacking header (body 8.5mm, pins 10.25mm)
- 2x20 male header
- nylon standoffs and nuts (2 of each)
When assembled it looks like this...
Large Clear Labels
As with all RasPiO boards, the connections are labelled in a large, easy-to-read font. There are also lots of options for adding extra headers or soldering wires to the board (to suit your project). The GPIO ports are broken out twice in addition to the two pHAT headers. There are extra holes for power and GND as well.
pre-Order Quantities & Bonuses
You can pre-order as many or as few as you like. Shipping rates are calculated by weight and have been kept low. There are some bonuses available for multiple pre-orders. Pre-ordering...
- 2 gets you a FREE bonus 6" RasPiO GPIO ruler
- 5 gets you a FREE bonus 12" RasPiO GPIO Zero ruler
- 10 gets you a FREE bonus Pi Zero W
Also, if you are quick, there's an early-bird offer for the first 100 purchases, but this is not limited to 1 per person, so feel free to grab as many as you like. Use the code EARLY at the checkout to get £1 discount per unit. This early-bird offer will expire after 100 uses or 24 hours, whichever occurs first.
If we hit 400 units I will upgrade the supplied stacking header to a custom-made header with full thickness pins.
What does that mean? Well the pins on the proposed stacking header are perfectly OK to use, but they are 0.6 x 0.4 mm which makes them a little bit more flexible (bendy) than those on a normal standard Pi header.
A standard Pi header has pins that are 0.64 x 0.64 mm. Most stacking headers are not 'square' like this, but have one side thinner.
Only this week I have found a potential source of the exact headers that I want. If we reach 400 units I will do my best to make sure the FullpHAT is supplied with this better header.
How the Process Works
Your card or PayPal account will be debited straight away. This is a pre-order. The RasPiO Full pHAT will ship within the next couple of months once the PCBs are made and components kitted (current estimate January 2018).
RasPiO Full pHAT will only go ahead if at least 200 units are pre-sold. I've used KickStarter for this sort of thing in the past, but decided not to this time to avoid bureaucracy and time delays on a relatively simple project.
Ideally I'd like to make a batch of 1000 or more because components like the stacking headers have a minimum order quantity of 1000. But the project will be viable (just) if there is enough interest to pre-sell 200 kits.
This campaign is running for 7 days, after which time I will order the next round of PCB prototype and the parts. If all goes well with that, I expect to ship in January.
Postage to Certain Countries
If you are ordering from Spain, South Africa or Brazil, please choose "International Tracked and Signed" delivery at the checkout. We have had regular problems with items going missing to these countries.
RasPiO FullpHAT is a HAT-sized board that enables you to connect 2 pHATs/HAT and break out available GPIO pins. Two pHATs is slightly (~4mm) wider than a HAT, so when you put two pHATs on, one of them will stick out a bit over the edge.
The stacking header will be 2x20 with the body 8.5mm high and the pins 10.25mm high. Remembering that the PCB is 1.6mm thick, this will leave 8.65mm protruding above the board. This is the same protrusion as a regular Raspberry Pi header.
The underside of the PCB is also labelled for your making convenience...
...it's much easier to solder wires to the right hole when it's labelled clearly!
Should you wish to make your project as 'low-profile' as possible you could solder the Full pHAT directly to the Pi and eliminate the main header altogether (works best with Pi Zero). But make sure you've done any soldering you need to on the underside of the PCB first.
Anticipated Project Timetable
It's possible that delays could happen if things go wrong, but this is a fairly simple project so I expect to be able to ship in January 2018.
