Proto-PIC - Electronic Component Supplier, based in UK is owned and operated by RelChron Limited which was founded in 2006.

We started the company to develop a product for the Oil Industry, a HydroStatic Pressure Testing System, which is still in wide use today.

During the development of this system, we accrued a whole pile of electronic goodies that we decided to sell on ebay to recoup some of the money we had spent. The items sold so fast we realised that there was a real need in the UK to buy electronics at good prices. We maxed out our credit cards and bought up lots of parts we thought there would be a need for in the UK and was born.

We buy electronics for the UK Maker Community in bulk from reputable suppliers only, generally from the USA. Buying in bulk allows us to be able to take care of all the Import tasks and paying Duty so the products can be available to customers in the UK on a super quick turnaround.

Our favorite supplier has to be Sparkfun Electronics in the US. They have been with us right from the beginning. Some of their components were in the original revision of our Pressure Testing System and they were the first guys we bought our first big (huge) order from to stock the place up. We sell every item that Sparkfun sell, unless its illegal to sell in the UK (some radio products are banned as they interfere with our wavelengths over here). Even if we are sold out of the item, we can get parts from them within 48 hours - if we place the order on Monday afternoon - it will generally be here Wednesday morning - that's pretty awesome!.

We knew that we had the ability and love of the products to be able to create some of our own. Our first in-house developed product was the Proto-PIC Arduino Starter Kit. We have sold over 10,000 of these to date. We now have a full range of products that are our own concept and design.

Our tech support team are fluent in Arduino C and can help with any aspect of design, code or assembly of your project.

The BBC Micro:bit is an ARM based embedded system developed by the BBC for use in education. It is aimed at getting kids into electronics - something very close to our hearts here - and can be programmed via a web interface. It has LEDs mounted on the board so kids can make scrolling messages or simple graphics. They can even connect up other things like temperature sensors using the croc clip rings on the board. We were really excited when we saw this and have lots of BBC micro:bit goodies in stock.

One of the things we learnt fairly quickly when we started out is that Packing efficiency is key. If you are selling fairly high value, fairly fragile parts - you want to pack them fast but protect them well. I was always concerned about ordering parts from websites and paying top money for shipping only for them to arrive having been dropped into a 7p Jiffy bag. We wanted to do something different. So we did our research and we have sent all our smaller orders in plastic boxes, since about 2010. This costs us a bit more, but we would be happier knowing that your items are extremely well protected during transit and just generally look nicer when you receive them. The boxes are meant to be reused by the customer, they can be used for storage - or can even be drilled and cut to make a nice enclosure. - We got such a great response from our boxes we now sell them as a stock item on the website.

Switches work like a dream. Arrived the next day, couldn't recommend enough.

A convenient kit to connect a breadboard power supply. More reliable than just inserting jump wires. Not pre-assembled, so skill required to solder tiny parts.

Happy Mark I WiFe.

Dead easy to put together, lovely little thing.

More good stuff for my toy box

An affordable board for extending experience and enjoyment of hobby electronics. Good service as well - next day delivery.

Needs better instructions.
Saturday, 10 February 2018  |  Anthony

I bought this thinking it would be a quirky giftfor my wife on Valentine's Day. The introductory video makes the construction process look simple and it is. However there are two things to look out for.

Firstly, nothing will prepare you for quite hwo small the parts are if this is your first SMD project. If your eyesight is anything less than perfect you will need some means of magnifying the board and parts while you work on them. I resorted to a lot of camera phone pictures when building mine as I could zoom in on those to inspect the work in progress.

Secondly, the LEDs that shipped with my kit were marked differently from the ones in the instruction video. Instead of a single green line at the cathode there was a green symbol which looked something life this: |- It looked to be in the centre of the part so I couldn't tell which end LED was which.

Just what I ordered

great service ordered Thursday night arrived Saturday. Brilliant

Great for younger children
Tuesday, 6 February 2018  |  Glyn

This is a great kit for younger children. No soldering is required so no burnt fingers! Perfect for teaching youngsters about electricity.

Great kit for intermediates
Tuesday, 6 February 2018  |  Glyn

A lovely kit for intermediates to have fun with.
I put this kit together with my daughter who is 10. She would have struggled with the surface mount elements on her own, but it gave me a chance to explain some more advanced soldering techniques to her.
When the kit was complete, we were very happy with the results.

Great beginners kit
Tuesday, 6 February 2018  |  Glyn

A lovely kit suitable for children aged 9 or 10 upwards. Myself and my son had a lot of fun soldering this kit and he has something 'real' to show for his work. Very happy.

Ideal for small projects
Monday, 5 February 2018  |  Anthony

These tiny breadboards are ideal for testing out new components and methods before incorporating into larger, more permanent soldered boards. They are small enough to use on robot vehicles where the self-stick base hold the board in place. I've used them in school and managed to fit 5 LEDs, 2 switches and an LDR onto one of these breadboards. Get the 5 pack - they are so useful.
