Field Trip! Hackaday Visits Pimoroni


If you have a Raspberry Pi and have any interest in its peripherals, you may be familiar with the grinning pirate logo of the British company, Pimoroni. The Sheffield, UK based outfit first established a niche for itself as one of the go-to places for much of the essentials of Pi ownership, and has extended its portfolio beyond the Pi into parts, boards, and components across the spectrum of electronic experimentation. Their products are notable for their distinctive and colourful design language as well as their  constant exploration of new ideas, and they have rapidly become one of those companies to watch in our sphere. On our way up to Newcastle for Maker Faire UK, we passed close enough to the Pimoroni HQ to be able to ask nicely if we could drop in and have a tour.

The Pimoroni HQ can be found in a nondescript unit with a discreetly placed sign on an industrial estate after a short drive through the city from the motorway. Inside it’s the same as thousands of other units, a set of offices at the front and a cavernous warehouse behind, except this one is filled with the kinds of goodies that get our blood pumping! And we’re told this toybox warehouse is soon to be joined by another nearby unit, as the Pimoroni business is expanding.

Our guide was the company co-founder Paul Beech, whose work you will be familiar with even if this is the first time you’ve heard his name;  Paul was the designer of the Raspberry Pi logo! The company is not exclusive to that platform but it’s fair to say they have a strong connection with the Pi, starting in 2012 with as their website puts it: “One laser cutter and a kettle” on which they produced the first of their iconic PiBow laser-cut sandwich Raspberry Pi cases.

We were first given a tour of their downstairs office, in which could be found alongside Paul’s eyrie, Tanya Fish who handles educational outreach, as well as Phil Howard who is responsible for the software behind the Pimoroni products. Straight away we were in to the interesting stuff, as the desks are laden with both the Pimoroni boards already out in the wild and quite a few in development that we hadn’t seen yet. This is an office you would definitely want to work in!

Upstairs is Mark, the buyer whose efforts keep the parts coming for Pimoroni’s production. The conversation turns to the global scale of the Pimoroni business, which now has a German operation as a complement to the Sheffield headquarters, and also sells a very significant percentage of its output to the USA.

In the next office is Niko, head of Engineering. This is where the hardware takes shape, and his desk is an electronics bench at which no doubt many Hackaday readers would be at home. We were shown some upcoming display panels and a yet-to-be-released breadboard power supply board with a hidden feature of being able to play Snake. An interesting conversation ensued about solderless connections, as they are also working with pogo pins and products with edge connectors. You may remember we reviewed Pimoroni’s solderless hammer-on pins last year, since some customers may not be confident with a soldering iron they are producing more products with that market in mind.

The warehouse side of the unit, currently houses both the mail-order and manufacturing sides of the business. Down the centre of the building lies their PCB production line, with a board loader,  solder paste printing machine, pick-and-place machine, and reflow oven connected by conveyor belts. This is a new line for them, we were also shown their first now-decommissioned pick-and-place machines, awaiting a new home.

The majority of Pimoroni’s modules are surface-mount, but they also maintain a wave soldering machine for their limited number of through-hole components. We tracked a panel of twelve individual HAT boards trough the machinery, watching LEDs being deposited at dizzying speed. Quality control is rigorous, with inspection between every link in the chain, and a reworking area to which boards are sent which don’t make the grade.

At the back of the unit to one side are the machines that long-time Pimoroni watchers might associate most with the company, their impressive line of laser cutters that fill one wall of the unit. These seemed to be mostly loaded up with PiBow parts during our tour, and are flanked by shelves containing an impressive array of acrylic sheet stock that would make any hackspace green with envy.

The manufacturing side of the company is only half of the story, because as well as a producing products they also operate a sizeable shipping operation. The half of their unit that isn’t occupied by the manufacturing facility is taken up with rows of storage shelves for their inventory, and the team who pack the Pimoroni kits, prepare the orders, and despatch them through Royal Mail to the customers.

We spent an entertaining minute peering into boxes here, finding everything from thousands of arcade buttons no doubt destined for PiCades, to bags of LEDs and stacks of neatly packaged Pimoroni HATs. If you have ever ordered a new Pi model from Pimoroni on its first day of release you’ve probably been pleasantly surprised by how quickly it is in the mail, these are the people we have to thank for that.

After saying goodbye and thanking our hosts for the tour, there was one more destination for the Pimoroni tourist. You can tell a lot about a company from its scrap bin, and since Hackaday writers are generally seasoned dumpster divers we headed across the parking lot for a look. In it were thousands of acrylic offcuts from their laser cutters, piles of neatly shaped small pieces of plastic in a rainbow of colours. Part of me is surprised that they don’t sell these by the pound to crafters, as it was we spent a minute or two playing guess the product from the part.

So we set off on our way northwards having had a fascinating morning on several levels. On one hand we’d seen some of the new products from a company that it’s fair to say are one of the Cool Kids in our world, but we’d also had a glimpse into a medium-scale electronic manufacturing facility as well as something of a potted history of the Pimoroni story from small beginnings to what is now a company with a global reach.
