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.


NEW! Unexpected Maker Help

I’ve just launched a new Knowledge Base website to help folks find answers to questions they have about my products. I’m adding content to it daily right now, so if there’s something you want to know, and you can’t find it there, please let me know!

NEW! NanoS3

I’ve just released my new NanoS3 boards! Don’t be fooled by it looking like a module, it’s a complete, feature packed ESP32-S3 microcontroller solution in a tiny 28x11mm package! It’s also drop in compatible with my TinyPICO Nano!

ESP32-S3 boards with u.FL

I’ve just released a new set of TinyS3, ProS3 and FeatherS3 boards with u.FL connectors instead of onboard antennas. This allows you to attach an external antenna for projects that need to go in cases/boxes or that need long range!

LoRa E5 Shield

This shield includes an E5 LoRa module from Seeed, that works in the EU868 / US915 / AU915 / AS923 / KR920 / IN865 range of frequencies and is compatible with the TinyPICO, TinyS2 and TinyS3

W.O.P.R is back in stock!!!

I finally have the W.O.P.R back in stock, and it’s an updated version with an improved 3D case and DEFCON digits!

Neo7 Mini Display

Brand new Mini Sized (34x20mm), Colourful, Bright & Animated RGB 7 Segment LED display boards. Now you have a choice in size between the Mini and the Original Neo7 Display!

RTC Logger Shield

Offering a super accurate, ultra low power Real time Clock (RTC) with a uSD card slot and 2x STEMMA/QT connectors (on 2 different IO pairs), this shield gives you the ultimate freedom for your data logging projects!

ESP32-S3 is here!

The ESP32-S3 is Espressif’s flagship MCU, with dual cores running at 240Mhz, WiFi, BLE 5,0 and more! I have three wonderful boards available that use this new chip - My Tinys3, FeatherS3 and ProS3.

Reflow Master Pro

Reflow Master Pro is an easy to install & feature packed solder paste reflow controller that can turn any suitable toaster oven into an SMD PCB reflow oven. Reflow Master Pro ships with a WiFi interface to allow you to control a huge range of settings and easily create and manage reflow profiles.

Shape Shape Shape


I have a YouTube channel, where I post project and product creation videos.
I also do weekly live streams where you can participate in the community chat to ask questions, offer help or just giggle along as I make a mess of things or get distracted… They’re pretty fun!

Below is a selection of some of my popular videos!


Here is a list of official resellers that stock some Unexpected Maker products!
If you are interested in stocking my products, please reach out to me for a chat!


Below are more Unexpected Maker websites you can visit for various products I make.

I release some of my projects as open source, and also share code examples and files for many projects. I also repositories containing supporting files for my products there as well. Have a scan through my repositories to see more!

Custom Design & Manufacturing

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!
