is directly connected to the 4 biggest component distributors on the electronics market: RS, Farnell, Digi-Key and Mouser. Therefore our algorithm can offer the best prices depending on availabilities, so that you can find what you need to complete your prototype project.

These suppliers were selected by our teams because of the quality of their customer service and the wide availability of electronic components they offer.


With over 80 years of experience in the electronics sector, Farnell Premier (founded in 1934 under the name Newark Electronics) proposes over 10 million components.

The company was bought by Avnet in 2016 to increase its global presence whereas Farnell element14, the branch specialised in development kits and prototyping assistance, arrived in 2010 (reference to the 14th element in Mendeleiev’s table).

With almost 20,000 employees, Farnell is present in over 125 countries and makes it a point of honour to support electronics players according to 4 key criteria:

  • Education & Makers: to support teachers and electronics enthusiasts by collaborating and discussing with them and providing solutions
  • Research & Design: to support startups and companies of any size using Farnell expertise to bring their ideas to life and help them to grow
  • Prototype & Test: to allow the fast development and creation of prototypes thanks to a vast selection of components, tools and equipment (Proto-Electronics obviously comes into this category)
  • Production & Maintenance: component prices are adjusted to demand and there is a top end service available.

Mouser Electronics

Western Components opened in 1964 in California before changing its name to Mouser Electronics. Since then it has become one of the electronic component leaders, supplying over 750 manufacturers. Mouser proposes passive and electromagnetic components, semi-conductors, interconnections… from its 25 production sites spread all over the world. They deliver over 600,000 clients every day in 220 countries and can process orders 24*7.
