Hello! My name is Seon, but most people know me as Unexpected Maker.
I’m based in Australia, and I design and manufacture my own range of microcontroller development boards, add on shields and other electronics based products that are enjoyed by hobbyists, enthusiasts and professionals around the world.
I also run a YouTube channel, and do weekly livestreams around electronics projects.
The latest news and product releases.
Visit the shop to see all of the products by Unexpected Maker.
The boards you already know and love, but re-invented to incorporate both onboard and external antenna options into a single board, with user controlled (via code) RF switch to select the antenna output for each project.

I release some of my projects as open source, and also share code examples and files for many projects. I also host repositories containing supporting files for my products as well. Have a scan through my repositories to see more!
My products often get used in product prototypes and projects where folks require design modifications to suit their requirements, or lower level integration of my designs into their products. If this interests you, please get in touch!
