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.

Good Value and Service

Great solution for enclosing an arduino

Very well made product that arrived when promised.
Easy to setup install. Just dril a hole of an appropriate size. Using a craft knife or a file, remove the small pieces in the corners to make the hole the correct size to accept a male connector.

Excellent service and fast delivery in very safe packaging.

Good, could be even better

Easy to make up - the PCB is printed nicely.

Instructions on the web site would help exploit this board. I used it to replace AA batteries for powering LED fairy lights - I had to file it down to fit in the battery compartment, and arrange the components to take minimal space, and fit a mcro usb (phone charging) socket which needs a bit of drilling. Alternate resistor values for changing the output voltage can be found here:

A satisfying project.

I am not the greatest when it comes to electronics and do most of my work using PIC's and just joining other things like motors! I have been using relays with great success but somebody suggested using Mosfets. After a bit of a learning curve I could see the advantage of using them in my projects and bought this Item which I cam across during a google search. The package arrived promptly and I assembled said parts with ease. I have tested it and it works so all in all very happy. I will be happy to purchase from Proto-Pic again. Thank you. It would be nice to have some single/dual boards as well!

Easy to solder and looks amazing. Although the LEDs are really bright so don't stare at them too long

This is a great little badge if you want to learn soldering! Its easy to solder the battery holder and the LED to the PCB. It shows you which way the components have to be attached to the PCB so you cant go wrong!

Its really eye catching and all of my friends ask me where I got it from!
