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 learned 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.

What can I say, faster than before, beautiful board and great starter kit.
Also Proto-pic are faster than Amazon, with much better packaging. Got a free project box out of the packing materials.

This is a must have micro:bit board for anyone wanting to control multiple servos. Well thought out and usable footprint. 10 stars??? Also very happy to have got mine so quickly from Proto-Pic and in incredible packaging! Thanks

Pololu wireless RC buddy module
Friday, 9 August 2019  |  Lawrence

This is an excellent product and similar to other 4 channel RC modules, but at a much lower price and with excellent quality. It is also much smaller. It allows you to use two receivers with a set of 4 servos, so you can use it as a wireless buddy trainer with two transmitters to control an RC plane - tutor and trainer options at the flick of a transmitter switch - your choice which switch. I used the gear channel.

In a class of its own

If you're reading this, my guess is that you've already made the same analysis as me. The Program-o-tron is a semipro tool -- maybe pro, if we're feeling generous -- in a market dominated by amateur kludges. There are any number of ATTINY programmers on eBay, but they are without exception extender boards built to work with other devices. That makes them awkward to use. While I'd prefer the Program-o-tron to be cased, it is completely standalone and can be rigged up securely in the middle of the workbench on a mousemat. 20 ATTINYs to program? No problemo! I wouldn't dream of using an alternative.

Good starter kit for young person
Friday, 26 July 2019  |  Conrad

Got this mostly because it looks nice, my 15 yo had trouble with the micro USB, the socket is a weird shape and bent the pins in cable, so it now has a dedicated "bent" USB cable

Great Product
