Embedded Systems Engineering
From circuit design and PCB layout to embedded firmware and prototype bring-up, AUBRIX Systems develops the electronics behind connected devices and control systems.

01 / Engineering services
Start with a bounded investigation, a specific implementation task or a phased hardware-and-firmware engagement.
For a prototype, design or firmware issue that needs a clearer technical direction before committing to a rebuild.
A scoped investigation, not a guaranteed diagnosis or fix.
For a defined feature, interface or control behaviour that your product needs to move forward.
ESP32, AVR, CAN, I2C, UART, MQTT and related interfaces.
For a custom controller or connected device requiring coordinated electrical design and firmware work.
Fabrication, parts, shipping and third-party testing are scoped separately.
02 / Selected engineering work
Three examples of hardware, firmware and integration work, with the contribution and project status made explicit.
01 / PCB and firmware development
A two board CAN system comprising a keypad transmitter and a relay output receiver. Firmware maps key events to actuator commands and handles key release.

02 / Firmware and hardware integration
A wireless Bingo display uses one ESP32 to control more than 10,000 WS2812 pixels. Game updates drive number highlighting through a map of the physical display.

03 / Firmware and prototype work
Compact ATtiny85 firmware for BlinkM style I2C commands, RGB and HSV fades, EEPROM scripts and motor patterns. Updates are organised without long blocking delays so command handling remains responsive.

Share your product, current stage and the problem. We identify the relevant files, constraints and decision-maker.
Where uncertainty is high, start with a paid investigation. Agree deliverables, exclusions and acceptance checks before implementation.
Work in agreed milestones. Review evidence and handle scope changes explicitly rather than letting them accumulate.
Review agreed tests, source/design files and build notes. Additional validation and support are scoped separately.
04 / ABOUT AUBRIX SYSTEMS
Custom PCB design, embedded firmware and hardware integration for connected devices and control systems.
AUBRIX Systems is led by Abu Bakar, a mechatronics engineer with firmware and PCB project experience since 2022 and a B.E. in Mechatronics from Air University. Technical work spans embedded C/C++, ESP32 and AVR controllers, device communications and custom electronics.
Projects are structured around agreed scope, technical reviews and documented handover.
Before we start
The strongest fit is a defined commercial controller, connected device, sensor/telemetry system or LED/control product. Share what exists and what needs to change; I’ll assess whether it matches my capabilities.
Yes, subject to a review of the files, ownership, interfaces and current behaviour. Inherited designs may need a bounded investigation before an implementation scope is reliable.
Both depend on scope, technical uncertainty and delivery capacity. Share your budget range and target date; commitments are agreed in a proposal, not assumed from an enquiry.
No. Start with a non-confidential summary. Any confidentiality agreement and appropriate file-sharing arrangements should be established before sensitive material is exchanged.
05 / Start a conversation
Send a short, non-confidential brief. Start with a project-fit review and a clearly scoped next step.
