Stores to find robot kits, electronic boards, motors and supplies for making or building your own gadgets used to be hard to find. I’ve collected a list of those I have found useful or plain fun here.


  • Pimoroni Pimoroni make and sell awesome robots and robotic gadgets. They are often updating, have a playful approach and some great videos. Great for kits, components and tools. They have a load of the DFRobot and Adafruit parts too.
  • 4Tronix have robots front and centre of their shop, always experimenting with robot chassis and control systems. They are the creator of The PiConZero board, an Orionrobots favourite for motor control. Great for Chassis, and breakout boards.
  • PiHut A great UK reseller of Raspberry Pi accessories, including boards, robotics components, makers stuff and micro:bit things.
  • Cool Components lots of electronics modules, tools and components. I’ve bought lots of neat gadgets to play and experiment with here. While they are not always the cheapest place, they are expert at what they do and have curated a very relevant range. Especially good with Arduino shields and compatible goodies. In their range are also 3d printers and CNC machines, servo motors, RF communications boards. They are London based but do not have a walk up store - they are exclusively web based.
  • Technobots Technobots have a very large range of electronic and mechanical parts. This includes most microcontroller types with shields and sensors, electronics components and hardware too.
  • RS, Farnell, CpC (now a Farnell subsidiary) and Rapid Electronics are traditionally trade electronic order catalogues. They’ve increasingly got hobbyist electronic parts like Arduino shields and Raspberry Pi stuff, as well as most components. They have walk up trade counters, but they can often deliver next day. These are better if you know what you want down to the part number, but want to find it online, in bulk or cheaper.
  • Robot Electronics I bought parts for making the EEBot here, they carry lots of controller boards and combination kits. My find was a complete drive chain - i2c based control board + motors + wheels + brackets and encoders in one kit. It meant making the EEbot was a doddle.
  • The PicAxe Store has plenty of sensors, PICAXE controller boards, robot kits etc. They carry a fast robot chassis that is the basis for the Micromouse robots.
  • Maplin are a shell of what they used to be. Useful in a pinch if you have a counter closer to you than RS, but they no longer have expert staff, and the ranges of electronics swing between the ludicrously dated and very faddish. They also seem overly keen on selling batteries to every customer trying to leave.
  • You will find many electronic and mechanical boards and bits on Amazon and Ebay if you look around. However - if doing so be very clear that you know exactly what you are getting and what level of support you will get for it. All of the Orionrobots Explorer kits come with our construction guides and I have built with them and interfaced them with my robots - if I can’t make it work, it doesn’t go on my shop or ebay listings.
  • Technology Will Save Us design and sell their own electronics kits which are really good fun. They are a great way to get started making. their website is no longer active though.

In The US

  • Adafruit - Adafruit make their own boards for electronics, gadgets and robotics. They resell other great stuff. They have awesome support forums and tutorials too!
  • create and sell their own Lego RCX sensors. Things like sensor multiplexors, interfaces for advanced sensors, they even stock I2C based devices, and a converter for the Lego RCX to talk I2C, expanding it hugely.
  • stock books, kits, components and complete robots.
  • Jameco Robot Store Mondotronics became the robot store, now part of Jameco. They have a large robot range, and I’ve bought kits of books from them in their former versions - like their excellent MuscleWires book.
  • The Junun Robot Store sells a kit that looks suitable as micromouse platform.

General tips

Toy shops, surplus electrical/electronic and mechanical stores are a good place to start.

Hobby shops, especially those with RC stuff always have a good supply of servos, although they might be more expensive than ordering online. Always keep a look out for good local hardware shops as well, screws and small sundry items as well as tools are conveniently available from these.

One way to find surplus stores and cheap places is to buy hobbyist magazines, which tend to have advertising and listings of these - often OrionRobots gets a small selection of Electronics, RC, miniature modelling and workshop magazines every now and again so we can get to know stockists.

Suppliers may contact us through the website to get themselves placed on this list, or for us to consider their products for our own shop. Products should be robot related kits and boards.

Lego Stores

Looking for the orionrobots store?

For a brief time, Orionrobots was selling robot kits, sensors and accessories. We are no longer doing this, and spending time on building, writing and making videos about robots!
