Embedded hardware
Board architecture, component selection, schematic capture, PCB layout, DFM, and prototype bring-up — with power, RF, and manufacturability considered from the start.

Engineered to endure.
SiliconBrane turns demanding connected-device ideas into working systems — hardware, bare-metal firmware, radio links, tools, and the infrastructure behind them.
What we build
Systems, not disconnected parts.
Strong products emerge when the electronics, firmware, radio behaviour, power budget, and deployment environment are designed together. That is the work SiliconBrane takes on.
Bare-metal firmware
Precise low-level C for constrained systems, including drivers, sleep states, interrupts, diagnostics, and the edge cases that determine field reliability.
LoRa, GNSS & BLE
Long-range telemetry and positioning systems that keep communicating beyond ordinary network coverage.
Prototype tooling
Purpose-built test fixtures, calibration tools, desktop utilities, and data capture workflows that make iteration measurable.
Edge & self-hosted systems
Linux services, containers, mapping stacks, build systems, and private infrastructure shaped around the product rather than bolted on later.
Technical investigation
Architecture reviews, failure analysis, pre-compliance thinking, and practical recommendations grounded in how the system actually behaves.
The throughline
One engineering conversation.
Instead of handing work from one silo to the next, SiliconBrane keeps the critical decisions connected from first architecture through bench validation.
Define the real constraints
Power, range, environment, cost, serviceability, interfaces, and production volume shape the design before parts are chosen.
Build the complete loop
Hardware and firmware advance together, with test access, logging, and repeatable bring-up built into the system.
Learn from the bench
Measurements replace assumptions. Each revision is driven by observed behaviour, not presentation-ready promises.
Hands-on R&D
Close to the hardware.
Good embedded engineering is physical. It happens with current probes, logic traces, revised layouts, hand-built fixtures, and firmware that has to wake up correctly every time.
This custom battery calibration fixture is typical of the approach: make the test repeatable, expose the variables, then let measurements guide the next decision.
Current products
Connected devices, built in-house.
SiliconBrane's product work spans practical control, environmental sensing, and off-grid location — each one shaped by real deployment constraints rather than a generic IoT template.
Lighting control
RGB LED controller
A dedicated control board for addressable RGB lighting, bringing power delivery, control logic, and firmware into one purposeful embedded design.
Distributed sensing
Temperature sensor nodes
Compact connected nodes for distributed temperature monitoring, designed around reliable sampling, efficient communication, and deployment where the measurements matter.
In development · LoRa + BLE + GNSS
Drover tracker
An off-grid location ecosystem: GNSS Nomad devices send positions over LoRa to a Drover hub, which forwards the group to a phone over Bluetooth — no cell service required.

Quietly rigorous.
The work is deliberately practical: understand the return path, measure the current, verify the footprint, and make the build reproducible.
Design decisions stay connected.
A radio choice changes power. A sleep strategy changes wake sources. A connector changes layout and enclosure. The system is treated as one thing.
Evidence over intuition.
Power profiles, link tests, DRC, logs, fixtures, and repeatable build steps turn “should work” into a result that can be examined.
Built for the next revision.
Clear layers, documented interfaces, reproducible environments, and thoughtful test access keep future work from starting over.
