i plus 1
electronics design house
Sydney / Hardware-first

Feats of
Engineering.

i plus 1 partners with teams to architect, prototype and ship electronics that behave like magic and ship like product.

Embedded Systems
IoT & Sensing
DFM-Ready Layouts
Concept → Schematics → Layout → Firmware → EVT / DVT.
Signal-Driven Design Systems
End-to-end electronics for ambitious teams
Prototron-grade rapid iteration

Iterate your Idea Faster., on demand.

From napkin sketch to production-ready PCB, i plus 1 plugs into your team as an external electronics brain. We specialise in low-power sensing, connected devices and tightly integrated mechanical + electrical systems.

01 / Core
Architecture & schematics

Requirements capture, power budgeting, silicon selection and robust mixed-signal schematics built for review and reuse.

02 / Layout
PCB & DFM

High-density digital, RF and precision analog layouts. Stackups, constraints and documentation tuned for your CM and test strategy.

03 / Firmware
embedded software

Bare-metal and RTOS firmware for connected devices, power-aware state machines and OTA-ready architectures.

04 / Lab
prototyping & validation

Bring-up, instrumentation and test rigs that close the loop between theory, simulation and the very real, very noisy world.

Mind-expanding workshops. Concrete output.

Every engagement starts with a focused technical workshop. We map the problem space, draw boundary conditions and leave with artefacts you can circulate internally: block diagrams, risk register, first-pass architecture and a delivery schedule.

01 / Diagnostic workshop
02 / Architecture + proof-of-concept
03 / Design & layout sprints
04 / Bring-up, test & handover
Engage i plus 1

Have a device that needs to exist in the world? Send a short brief with your constraints, timelines and any prior work. We will respond with a suggested engagement format within two business days.
