That's excellent news :)
Means that schools can now order them for class use :)

They'd want them with headers anyway

Pity the incremental price of the header more than doubles the cost of the original Zero but if they are not being done in the factory at production time then I can see that firms like ModMyPi need to factor in the time and effort for them to do it themselves.

And increase their previous profit margin of 1p/unit of course :)

Wonder if they are wave soldered or hand solder.
Hand soldered? then they are a bargain at that price :o
Let's all buy 50 each, watch supply dry up.

Wonder if this is the "announcement soon"?
Wait till tomorrows blog post, "only available to Code clubs" :lol:

I will try to contain my excitement.

So, working from the above...

Theory #1: a major factor in Pi Zeros having been so scarce is that at the $5 price point, there's vanishingly little money to be made from them by the traditional commercial producers. Adding the header is a useful addition, and provides a reason to release a variant at a more sustainable price point, so the big players can make some big batches.

Theory #2: sort of the theory above, but with the specific motivation that for things like Code Club, when introducing new students to physical computing, maybe it's best not to start off with, "for your very first task, this is a soldering iron, you need to solder on this header, making 40 perfect solder connections without damaging anything, and this is pass/fail, as these connections will control whether any future project works." Kind of a troublesome initial hurdle to give students, thus, best to start with boards with pre-soldered headers.

Theory #3: Taking in other recent news, if WD Labs is, indeed, getting out of the Pi accessory business, given that they had at least one product that came with a Pi Zero (and perhaps plans to do similar with the Pi Zero W), maybe a completed-but-no-longer-required batch of a few thousand "extra" Pi Zeros and Zero W's suddenly became available, and ModMyPi bought it up. Surely WD Labs was ordering them in quantity and with headers, rather than having techs sit around hand soldering. Maybe ModMyPi even bought them from WD Labs rather than from the factory.

In any case, good to see that there's a bunch available (at least for now), for all those folks who were saying, "I really have to get a bunch for (plans to take over the world)". For quantity 1 or 2, likely it's still cheaper to buy the regular way, but for quantity 10, this would be a win.

Some fun with numbers...

(Doing the math for delivery to the USA, because first, that's where I am, and second, they have free shipping in the UK, so this is moot there. Also, once I ran through their shipping calculator and indicated I was in the USA, and then chose "$" for currency up at the top of the page, their system showed me all further pricing in USD, without the UK taxes, aka "Ex Vat". So the currency conversion is ModMyPi's.)

First off, they have 3 shipping methods, some of which are unavailable for some items/quantities (don't know if that's based on size, weight, cost, or other factors):

+ $6.75 for "Global Airmail (5-15 Working Days)"
+ $10.79 for "Airmail Global Tracked. (3-15 Working Days)"
+ $53.99 for "DHL Express (1-4 Working Days)"

Next, the Pi's (their system removed cheaper shipping methods for larger quantities at various points; and the UK prices are with tax and generally have free shipping, while the US prices are "Ex.Tax"):

Pi Zero: £4.80 ($5.40), with 1184 in stock
@ qty 1: Global Airmail: $6.75

Pi Zero W: £9.60 ($10.80), with 426 in stock
@ qty 1: Global Airmail: $6.75

Pi Zero w/header: £9.95 ($11.19), with 185 in stock
@ qty 1-2: Global Airmail: $6.75
@ qty 3-30: Airmail Global Tracked: $10.79
@ qty 31-50: DHL Express: $53.99

Pi Zero W w/header: £13.99 ($15.74), with 179 in stock
@ qty 1: Global Airmail: $6.75
@ qty 2-21: Airmail Global Tracked: $10.79
@ qty 22-50: DHL Express: $53.99

Also note that from ModMyPi you can now buy a ClusterHat pre-populated with four Pi Zeros (plus four 16GB Micro SD Cards) now for £89.99 ($101.24), none in stock.

(Also, I noticed a "Follow us for a 2% Discount" note at the top of their pages. I didn't figure that into any of this.)

So... with the numbers above, I wrote a script to figure out how the prices compared, because I was curious (I have enough of both for now, not contemplating a mass purchase).

Looks like the bulk purchase makes sense for ordering between 12 and 30 Pi Zeros, and for ordering 6-21 or 30-50 Zero W's. In the other cases, you're better off, cost-wise, ordering individual units, even though more effort is involved. For the Zero it looks like you're best off ordering large quantities precisely 30 at a time. For the Zero W, 50 at a time is the least expensive.

And, for the folks figuring that Zeros bought individually cost "about double" (i.e. shipping is roughly as much as the Zero), and thus buying in bulk should mean saving nearly 50%... well, the best deal here, buying 50 Zero W's for $877.50, saves $36.51, or about 4%. Still, you can get one big box full of Zeros, which is more convenient than a desk buried in padded envelopes.

Here's the table I generated...

Code: Select all

#:  Zero       ?? Zero+hdr   diff   | Zero W     ?? Zero W+hdr diff

I'm pretty sure its based on cost, their insurance covers deliveries to a certain value, above that a registered delivery service has to be used to provide supplementary insurance coverage.

I have to say that I love ModMyPi, their customer service is really good.

Yes, but that's embargoed due to it being effectively a loss leader*
(* yes apparently it has some minimal profit but same principle applies )

With the lifting of the 1 per customer limit (for presoldered) it now becomes a proper product IMO

Is there some official announcement about this? Haven't seen any. Will other shops follow or is this modmypi exclusive (and possibly limited) offer?

Personally I do not want presoldered header as I want to solder female or angled one to have it thinner and also getting it in single quantities is still cheaper including shipping than this, but indeed it is ideal for schools, clubs etc. which is great :-)

I'm not sure if the one per order is a restriction for education establishments (but you do need to ask direct to pimoroni/pi-hut etc as by their FAQ's about that, I've not tried).

Zero loss leader (proof of concept, detrimental effect on Pi3 etc profit).
ZeroW is not the same, that'll be demand creating restrictions so far. Otherwise they end up like consoles and popular graphics cards or phones where nobody can buy them and everyone get annoyed or looks somewhere else.

they are down to 153 in stock so that was a very accurate statement. The maximum order quantity has now dropped to 20.

ModMyPi announced it in their Newsletter but it's not been shouted about (I saw it here, it wasn't announced on their forums).

A couple of weeks ago I saw a listing on another supplier, one of the recent additions in the US, that was offering Pi0 and Pi0W with pre-soldered headers for $5 more (in each case) than the bare board. I don't recall/didn't check if they would sell multiples, though.

So...it's possible this is a "thing". Perhaps it's what the RPT is doing to make more available (in the sense of higher margins though the whole chain making production more attractive). Or it might be an experiment. In either case, just as there was no formal announcement of the change from the Pi2B to the Pi2B2, this might be considered too minor to be worth comment.

If these are going to be a continuing and spreading (among vendors) products, perhaps it will ease the demand pressure on the bare boards. Or perhaps not. Only time will tell. If it does fix the demand/supply imbalance, we can move on to wondering when the Pi3A will appear.

I would think that the A+ or even one of the current B-series Pis would be a far better choice for starting out with Code Club projects, and not just because the headers are already in place. I will concede, though, that having pre-soldered headers narrows the margin by which I consider the Pi0/Pi0W not to be beginner Pis.

There's an article in MagPi Magazine issue 59.
Online retailer Pi Supply (pi-supply.com) has released a Raspberry Pi Zero W with a GPIO
header. .... We wondered who was doing all the laborious soldering: “For the first 100 units, we did these by hand
between four of us… we have now outsourced it to our lovely contract manufacture partners based in the UK.”
